s390/debug: Fix NULL pointer dereference in debug_set_level()
Commit a2cec6863709 ("s390/debug: Add s390dbf kernel parameter")
incorrectly removed a null-id check from debug_set_level(), introducing
a possible NULL pointer dereference for debug-API users that put
debug_register() results unchecked into debug_set_level().
Fix this by moving the check from the internal _debug_set_level()
variant back to the external debug_set_level() wrapper. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: flowlabel: cap duplicate leases per socket
ipv6_flowlabel_get() allocates an ipv6_fl_socklist entry for every
successful GET. The recheck path for a compatible existing flowlabel
links another lease without applying any lease admission check. Repeated
GET requests for one shareable label can therefore grow a socket's lease
list without bound.
Reject a new unprivileged lease once the socket already holds
FL_MAX_PER_SOCK leases. Check this on the shared recheck path so reuse
of a globally interned label, including the fl_intern() collision path,
is covered as well. New-label admission remains under the existing
mem_check() policy.
Use capable(CAP_NET_ADMIN) rather than ns_capable(), matching
mem_check(). An unprivileged user must not bypass the cap by creating a
user namespace and a netns where they have CAP_NET_ADMIN, which would
still consume host memory.
Check the capability only when the socket reaches the limit, so
successful unprivileged GET requests below the cap do not generate a
capability audit. Do the admission check before updating linger and
expires so a rejected GET does not refresh the shared label, matching
the existing socket-list allocation failure path. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: fib: bound automatic table ID allocation
fib_empty_table() probes every table ID from 1 until it finds a
free one. IPv4 tables are stored in a 256-bucket hash table, so a
dense set of IDs makes each probe walk a growing hash chain while
RTNL is held.
Automatic table assignment ("ip rule ... table 0") is an IPv4-only
legacy path. Bound the automatically allocated ID to 4096 so the
RTNL hold stays bounded, without changing lookups of explicitly
specified table IDs.
This changes user-visible behavior. A table-0 rule previously
received the lowest free ID in 1..RT_TABLE_MAX (0xFFFFFFFF). After
this patch the search stops at 4096 and the rule add fails with
ENOBUFS if that range is fully occupied. Explicit table IDs above
4096 remain usable.
The automatic path is unused in practice: it is IPv4-only, not
documented by ip-rule, uncovered by kernel selftests, and both
NetworkManager and systemd refuse table 0. |
| In the Linux kernel, the following vulnerability has been resolved:
ieee802154: cc2520: fix FIFOP work use-after-free
The FIFOP interrupt handler queues cc2520_fifop_irqwork. On removal,
cc2520_remove() only flushes the work. The devm-managed FIFOP IRQ
remains active until after ->remove() returns and can queue the work
again after that flush, allowing it to run after the private data is
released.
Disable the work with disable_work_sync() instead of flushing it, so
the handler can no longer queue it once removal begins. Destroy the
buffer mutex last, since the worker and the stop callback invoked
through ieee802154_unregister_hw() both take it.

| MCP Atlassian is a Model Context Protocol (MCP) server for Atlassian products (Confluence and Jira). Prior to 0.22.0, caller-supplied projects_filter and spaces_filter arguments can replace administrator-configured allowlists, and caller-provided project or space clauses can suppress the configured restriction. A caller can search projects or spaces outside the intended boundary when the configured Atlassian credentials can access them. The advisory traces the vulnerable input and processing flow through JIRA_PROJECTS_FILTER, CONFLUENCE_SPACES_FILTER, projects_filter, spaces_filter, SearchMixin.search_issues, and SearchMixin.search, which identify the affected entry points, controls, and code paths. This issue is fixed in version 0.22.0. |

Prior to 0.22.0, _make_ssrf_safe_hook is omitted from JiraFetcher and ConfluenceFetcher sessions created through the basic-auth and oauth_pat branches. If an attacker-controlled or compromised configured Atlassian instance returns a redirect to an internal address, those sessions can follow the redirect without revalidating its destination.

| In the Linux kernel, the following vulnerability has been resolved:
sched/rt,dl: Skip migrate-disabled tasks when picking a push candidate
A migrate_disable()'d RT task cannot be moved to another CPU, but the
scheduler still keeps such a task on that CPU's pushable list
(rq->rt.pushable_tasks) and still marks the runqueue RT-overloaded
(rq->rt.overloaded = 1). So the RT balancer keeps treating this CPU as
having a task to move away, and keeps trying to move the task, but the
push can never succeed. When the head is pinned, push_rt_task() does not
give up either. It falls back to pushing rq->curr instead, using the
per-CPU stopper, as added by commit a7c81556ec4d ("sched: Fix
migrate_disable() vs rt/dl balancing").
The CPU spends tens of milliseconds in this retry loop. The core is
isolated for real-time work, but during the loop nearly half of its time
is consumed by pushes that cannot succeed.
An ftrace capture of the affected CPU, with sched_switch enabled and
commit 94894c9c477e ("sched/rt: Skip currently executing CPU in
rto_next_cpu()") applied, shows where the CPU time went. Two SCHED_FIFO
tasks at equal priority shared the CPU, taskA migrate_disable()'d and
queued, taskB as rq->curr. In one 89 ms window, taskB got only 52 ms of
CPU. The other 37 ms went to the stopper thread.
The scheduler kept trying to push taskA, the pinned head of the pushable
list, fell back to pushing taskB instead, and woke the stopper 5204
times. Every one of those pushes failed and no task was moved. taskA
stayed runnable and queued the whole time, and never ran.
Pushing taskB fails on a re-check. find_lock_lowest_rq() drops the rq
lock to take the target rq lock, then checks again with
"task != pick_next_pushable_task(rq)".
The task being pushed is taskB, but the pick returns taskA, the head of
the pushable list. taskB is rq->curr, and set_next_task_rt() removes the
running task from that list, so taskB can never be the head. The check
expects a candidate taken from the pushable list, but the fallback
pushes rq->curr, which is never on that list. So the check fails every
time.

'----------'
repeats every ~17 us, 5204 times, for 89 ms
The loop cannot stop itself. Every round leaves the runqueue
exactly as it was, so the next push-IPI does the same thing. In
the capture it ended only when taskB went to sleep on its own.
taskA was then picked locally and left the pushable list.
CPU time per task in the window, from sched_switch:
taskB 51.95 ms real work
migration/N 37.18 ms nothing moved
taskA 0.00 ms queued the whole time, never picked
idle 0.01 ms
Counts over the same window:
7667 push-IPIs handled on this CPU
17481 pick_next_pushable_task() returned taskA, still pinned
5204 find_lock_lowest_rq() gave up on the re-check
1 push that actually completed
0 migrations of taskA
The CPU times and the window length come from the standard
sched_switch tracepoint. The counts needed tracepoints added inside
the RT balancer for this investigation.
The self-IPI path is closed by the rto_next_cpu() fix above, and that
part works. But the runqueue is still marked overloaded, because the
pinned task is still advertised as pushable. Other CPUs now send the
push-IPIs during their own RT balancing, and the same loop runs again.

| In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix xmit_frame/xmit_buf leaks on mgnt-frame error paths
issue_beacon(), issue_probersp() and issue_asocrsp() obtain a management
xmit_frame together with its xmit_buf from the driver's fixed-size
management-TX pools via alloc_mgtxmitframe(). On the normal path the frame
is handed to dump_mgntframe(), which transfers ownership and eventually
returns both objects to their pools (the frame and, for beacons, the buf
in rtl8723bs_mgnt_xmit(); other bufs via the pending-xmitbuf/TX-completion
path).
Several error/edge paths return early after a successful
alloc_mgtxmitframe() but before dump_mgntframe(), so ownership is never
transferred and neither object is freed:
- issue_beacon(): beacon larger than 512 bytes
- issue_probersp(): cur_network->ie_length > MAX_IE_SZ
- issue_probersp(): kzalloc() of the SSID scratch buffer fails
- issue_asocrsp(): pkt_type is neither ASSOCRSP nor REASSOCRSP
Because alloc_mgtxmitframe() removes the frame and buf from their free
lists (list_del_init) without placing them on any pending list, an
orphaned pair is on no list and referenced by nobody, so it is only
reclaimed at driver teardown. Repeated hits progressively exhaust the
management-TX pools until alloc_mgtxmitframe() returns NULL and the
interface can no longer send beacons or probe/assoc responses.
Free the frame and buffer on these paths, matching the existing correct
error handling in issue_assocreq(). |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: accurately adjust free_sections during free_segment_range
In free_segment_range(), MAIN_SECS(sbi) is temporarily reduced by `secs`
to restrict block allocation to the safe remaining main area while valid
blocks in the truncated range are evacuated by GC.
However, FREE_I(sbi)->free_sections tracks the total number of free
sections across the whole filesystem. If any sections within the
truncated range were already free upon entering free_segment_range(),
failing to deduct them from free_sections causes the filesystem to
overestimate available free sections in the active, reduced main area.
This leads to inconsistent free section accounting during GC data
migration and can trigger unexpected allocation failures or assertion
errors when space is tight.
Fix this by calculating the number of already-free sections in the
truncated range, deducting them from free_sections upon entering
free_segment_range(), and restoring them on exit. |
| Use after free in Remote Desktop Client allows an unauthorized attacker to execute code over a network. |
| The Botslab G980H dash camera firmware contains an authentication vulnerability in the root account exposed through the device's UART interface. The affected account does not require a password before granting access to a privileged system interface, and the interface also displays the device's WiFi password during startup. An unauthenticated attacker with physical access to the device could connect to the UART interface, obtain root privileges, and recover the WiFi password. |
| The Botslab G980H dash camera firmware generates the default WiFi password using predictable device information, portions of which are advertised by the product. An unauthenticated attacker within WiFi range could potentially determine the remaining password characters through limited guessing and gain unauthorized access to the device network. |
| Uncontrolled Resource Consumption (CWE-400 / CWE-407) in the ANTLR 3 search query parser (QueryParser / Query.g) in Gerrit Code Review versions 2.0.19 through 3.12.9, 3.13.0 through 3.13.8, and 3.14.0 through 3.14.2 allows an unauthenticated remote attacker (or an authenticated user if anonymous read access is disabled) to cause a persistent denial of service (CPU exhaustion and HTTP worker thread pool starvation requiring a server restart) via crafted search queries containing deeply nested parentheses sent to query evaluation endpoints (/changes/?q=, /accounts/?q=, /groups/?query=, /projects/?query=, /Documentation/?q=, /changes/{id}/query?expression=, or SSH gerrit query). Because syntactic predicates in conditionOr and conditionAnd recurse via conditionBase without memoization prior to capability or visibility checks and worker threads do not abort when the client disconnects, a small number of requests (such as 25 requests matching default httpd.maxThreads) can permanently pin all HTTP worker threads. This issue is fixed in Gerrit Code Review versions 3.12.10, 3.13.9, and 3.14.3. |
| Incorrect Authorization (CWE-863) in project name normalization (ProjectUtil.stripGitSuffix) and ProjectCache eviction logic (ProjectCacheImpl) in Gerrit Code Review versions 2.16.0 through 3.12.9, 3.13.0 through 3.13.8, and 3.14.0 through 3.14.2 allows an authenticated user (or an unauthenticated user if the repository was previously public) to cause unauthorized disclosure of private repository content and durable restoration of revoked project-owner administrative privileges via crafted requests using repeated .git suffixes (such as project.git.git) across REST APIs, Gitiles, or SSH Git commands. Because Gerrit strips only a single terminal .git suffix when constructing the logical ProjectCache key while JGit (FileKey.lenient) resolves the suffixed alias to the same canonical bare repository on disk, revoking read access or removing owner rules on the canonical project name fails to evict the cached alias ProjectState during the cache validity window, enabling reads of newly created private commits or writes to refs/meta/config. This issue is fixed in Gerrit Code Review versions 3.12.10, 3.13.9, and 3.14.3. |
| The Botslab G980H dash camera firmware contains an out of bounds write vulnerability in its command processing functionality. An authenticated attacker with adjacent network access could submit crafted command data that corrupts memory, potentially disrupting authentication state or causing the affected process to terminate and the device to restart, resulting in a temporary denial of service. |
| The Botslab G980H dash camera firmware does not require authenticated pairing or client binding before permitting access to Bluetooth Low Energy communications and GATT characteristics. An unauthenticated attacker within Bluetooth range could intercept or directly retrieve sensitive device information, including device identifiers, firmware information, and protected WiFi credentials. |
| Secure Folder 1.2 stores files selected for its password-protected vault as unencrypted files in the Android shared-storage tree. A local application or file manager that has access to the relevant shared-storage path can enumerate, copy, and open those files without authenticating to Secure Folder. |
| The Botslab G980H dash camera firmware does not adequately verify the authenticity of firmware updates. The update process retrieves firmware through an unprotected connection and relies on an integrity value supplied with the firmware instead of a trusted cryptographic signature. A suitably positioned attacker who intercepts a firmware download, or an authenticated attacker who submits a crafted update, could install modified firmware and execute unauthorized code on the device. |
| The Botslab G980H dash camera firmware contains a hard-coded root account password that cannot be changed by the user. An attacker who obtains the firmware or has physical access to the device could recover the credential and use it to obtain root access through the UART interface. |
| The Botslab G980H dash camera firmware accepts a reusable authentication value without adequately verifying its freshness or association with the requesting client. An unauthenticated attacker with adjacent network access who captures a valid authentication value could replay it from another client to establish an authenticated session and access privileged device functionality. |
