CVSS v3.1 |
| A vulnerability in the Gemini CLI prior to version 0.39.1 allows attackers to achieve arbitrary code execution by tricking a victim into starting the CLI within an untrusted directory. The vulnerability is triggered via untrusted .env files overriding GEMINI_CLI_HOME to load malicious configuration files and bypass folder trust prompts. |
| ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact (e.g., a crash of the affected process). The issue is fixed in versions 7.1.2-31 and 6.9.13-56. |
| Memory Corruption when copying large input data exceeds normal allocation limits. |
| Memory corruption while processing rear sensor IOCTL calls. |
| Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. From 1.4.0 until 3.7.2, packages/renderer/MdToHtml/rules/katex.ts enables KaTeX's trust option for note content, allowing a note author to place a \href URL into rendered output without passing Joplin's normal URL allowlist. On Windows, clicking a link whose target is an attacker-controlled UNC path causes pathExists() to initiate SMB authentication and disclose the current user's NTLMv2 challenge-response without a warning. The unfiltered URL can also invoke other registered URL handlers, but the credential disclosure through KaTeX \href is the distinguishing demonstrated impact. This issue is fixed in version 3.7.2. |
| A weakness has been identified in ColorFul iGameCenter 1.0.3.4. This impacts the function sub_140001AF0 in the library ene.sys of the component IOCTL Handler. This manipulation causes untrusted pointer dereference. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. |
| Untrusted Pointer Dereference vulnerability in RTI Connext Professional (Core Libraries) allows Pointer Manipulation. This issue affects Connext Professional: from 7.4.0 before 7.6.0, from 7.0.0 before 7.3.0.10, from 6.1.0 before 6.1.2.27, from 6.0.0 before 6.0.1.43, from 5.3.0 before 5.3.*, from 5.2.0 before 5.2.*, from 4.4a before 5.1.*. |
| Untrusted Pointer Dereference vulnerability in RTI Connext Professional (Core Libraries) allows Pointer Manipulation. This issue affects Connext Professional: from 7.4.0 before 7.6.0, from 7.2.0 before 7.3.0.9. |
| Untrusted pointer dereference in Windows Group Policy allows an authorized attacker to elevate privileges over a network. |
| NetBox Device Type Library is a collection of community-sourced device type definitions for import into NetBox. The validation test harness can deserialize pull-request-controlled tracked pickle cache files through pickle.load in the read_pickle_data function in tests/pickle_operations.py. An unauthenticated contributor can change USE_LOCAL_KNOWN_SLUGS in tests/test_configuration.py and supply a crafted tests/known-modules.pickle or tests/known-racks.pickle file that tests/definitions_test.py loads when pytest runs. Deserialization invokes attacker-controlled object reduction behavior, allowing arbitrary code execution in the GitHub Actions runner or in a maintainer process that runs the tests, with the confidentiality, integrity, and availability of reachable resources at risk. This vulnerability is fixed with commit 1c6f7e2b93589b965318c6e67ac3504831f0e71e. |
| FreeRDP versions before 3.31.0 contain an information disclosure vulnerability in the RDPGFX server's ResetGraphics PDU serializer that fails to initialize padding bytes in the fixed 340-byte wire format. Attackers can receive uninitialized heap memory including live pointers and GLib function addresses transmitted in the PDU, defeating heap ASLR and disclosing the GLib module base address. |
| Mistral Vibe before 2.25.5 contains a remote code execution vulnerability in the worktree creation process that executes git hooks before trust validation. Attackers can supply a repository with a crafted post-checkout hook that executes arbitrary shell commands with the privileges of the user running Vibe. |

KEYS: trusted: Fix TPM teardown ordering
trusted_tpm_exit() drops the TPM chip reference and frees the digest
array before unregistering the trusted key type. key_type_lookup()
holds key_types_sem for reading until the key operation finishes, while
unregister_key_type() takes it for writing. It therefore provides the
synchronization point that must precede backend teardown.
The current order permits this interleaving:
CPU 0 CPU 1
trusted_tpm_exit() key_type_lookup("trusted")
put_device(&chip->dev) trusted_tpm_seal()
kfree(digests) pcrlock()
unregister_key_type() tpm_pcr_extend(..., digests)
CPU 1 can consequently dereference the freed digest array. The chip can
also be released before callbacks stop using it.
KASAN reported:

mm/migrate_device: clear stale mapping after freeing swapcache
__migrate_device_pages() reads the folio mapping before calling
folio_free_swap(). When folio_free_swap() succeeds, the folio is removed
from the swap cache, but the saved mapping still points to swap_space.
Passing the stale mapping to folio_migrate_mapping() makes it use the
mapped-folio path for a folio that is no longer in swapcache. It can then
operate on swap_space.i_pages with invalid reference accounting,
eventually triggering a folio reference count BUG.
After a successful split, nr still contains the number of pages in the
original large folio, although each resulting page is now a separate
order-0 folio. Reset nr to 1 so each split folio is processed separately,
including its own swapcache removal and mapping lookup.
Refresh the saved mapping after folio_free_swap() so the current folio
state is used during migration. |

nfsd: RCU-protect cl_cb_session to fix use-after-free on session teardown
After a DESTROY_SESSION the per-session teardown path can free a
session while rpciod still holds an inflight callback rpc_task that
dereferences clp->cl_cb_session. nfsd4_probe_callback_sync() flushes
cl_callback_wq, but once nfsd4_run_cb_work() has called
rpc_call_async() the rpc_task lives on rpciod; flushing the workqueue
does not wait for it. rpc_shutdown_client() does drain rpciod tasks,
but uses a 1-second wait_event_timeout — tasks stuck in rpc_delay()
(e.g. 2-second NFS4ERR_DELAY retries) can outlive the drain.
destroy path rpciod
------------ ------
unhash_session(ses)
nfsd4_probe_callback_sync(clp)
flush_workqueue(cl_callback_wq)
/* returns; rpc_task still live */
nfsd4_put_session_locked(ses)
free_session(ses) -> kfree(ses)
nfsd4_cb_sequence_done()
reads cb_clp->cl_cb_session
/* freed slab */
A second window exists in nfsd4_process_cb_update(). When
__nfsd4_find_backchannel() returns NULL because unhash_session() has
already removed the destroyed session from cl_sessions,
setup_callback_client() takes the v4.1 early return so
clp->cl_cb_session = ses never fires and the field retains a pointer
to the about-to-be-freed session.
Fix both by converting cl_cb_session to an RCU-protected pointer:
- Move the cl_cb_session = ses assignment in setup_callback_client()
to after rpc_create() succeeds, so it is only published when a
working backchannel exists. Clear cl_cb_session on the error
return in nfsd4_process_cb_update(). Both stores use
rcu_assign_pointer().
- Annotate cl_cb_session with __rcu. All rpciod-side readers use
rcu_read_lock()/rcu_dereference() and check for NULL, bailing to
the appropriate error or requeue path:
encode_cb_sequence4args(), decode_cb_sequence4resok(),
nfsd41_cb_get_slot(), nfsd41_cb_release_slot(),
nfsd4_cb_prepare(), and nfsd4_cb_sequence_done().
- Switch __free_session() from kfree() to kfree_rcu() so the
session slab is not reclaimed until after an RCU grace period,
guaranteeing that rpciod readers inside rcu_read_lock() never
dereference freed memory.
- Pass the session pointer to the nfsd_cb_seq_status and
nfsd_cb_free_slot tracepoints instead of having them re-read
cl_cb_session.
- nfsd4_cb_prepare() calls rpc_exit() when the session is NULL,
routing through the done/release path to requeue the callback. |

nfsd: fix stale s2s_cp_stateids IDR entry for async COPY
For an async COPY, nfsd4_copy() called nfs4_init_copy_state() before
dup_copy_fields(), so the s2s_cp_stateids IDR was pointed at
&u->copy->cp_stateid -- memory in the per-rqstp COMPOUND buffer that is
reused by the next request. dup_copy_fields() copies only the value into
async_copy, so the IDR slot dangled at the transient buffer for the whole
background copy. Any IDR walker then dereferences reused request memory:
the laundromat reads cs_type from it and, if the bytes look like an
expired NFS4_COPYNOTIFY_STID, follows into
refcount_dec()/idr_remove()/kfree() on garbage; manage_cpntf_state() has
the same exposure via idr_find().
Duplicate the fields first, then register the stateid on the stable
async_copy. result->cb_stateid is unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Prevent client use-after-free during admin state revocation
A stateid holds only a bare pointer to its nfs4_client; a stateid
reference does not pin it. The client survives only because
__destroy_client() drains its stateids before free_client() runs.
nfsd4_revoke_states() drops nn->client_lock across revoke_one_stid(),
which dereferences the client to revoke a stateid and read
clp->cl_minorversion. A teardown racing the dropped lock can free
the client first.
Pinning cl_rpc_users under client_lock blocks the DESTROY_CLIENTID and
EXCHANGE_ID teardown, which refuses while cl_rpc_users is non-zero.
force_expire_client() ignores it: once its wait for cl_rpc_users to
reach zero has passed, a later pin goes unnoticed.
Under client_lock, skip a client whose cl_time is already zero --
force_expire_client() clears it there before waiting -- otherwise pin
cl_rpc_users before dropping the lock. The walk then either sees the
expiry and skips, or pins in time for that wait to cover the revoke. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Prevent client use-after-free during delegation revoke
A delegation stateid holds only a bare pointer to its owning
nfs4_client and does not keep it alive. The client survives its
stateids only because __destroy_client() drains cl_delegations and
cl_revoked before free_client() runs.
nfs4_laundromat() breaks that invariant: it unhashes an
expired delegation from cl_delegations, drops deleg_lock, then
revoke_delegation() relinks it onto cl_revoked under cl_lock. In that
window the delegation is on neither list, so client_has_state() can
report no remaining state.
Every teardown path first requires cl_rpc_users to be zero, but
the laundromat holds no such reference. A client whose recalled
delegation has just timed out can therefore reach free_client()
while revoke_delegation() is still about to dereference cl_lock,
a use-after-free.
Pin the client with cl_rpc_users across the revoke so teardown blocks
until it completes, then reap the delegation from cl_revoked. A client
already expiring reaps its own, so skip it and leave the delegation on
del_recall_lru. |

HID: universal-pidff: stop the device when force-feedback init fails
universal_pidff_probe() starts the device with hid_hw_start() and then, if
force-feedback initialisation fails, returns the error through a label that
only does "return error". The device is left started.
The HID core does not unwind on the driver's behalf. __hid_device_probe()
releases the devres group, closes the report and clears hdev->driver:
if (ret) {
devres_release_group(&hdev->dev, hdev->devres_group_id);
hid_close_report(hdev);
hdev->driver = NULL;
}
The hidraw character device that hid_hw_start() registered through
hid_connect() is allocated with kzalloc() and added with cdev_device_add(),
so it is not devres-managed and survives that. With hdev->driver NULL,
hid_device_remove() skips hid_hw_stop() as well, because it only unwinds
while a driver is still attached. The registration therefore outlives the
device on both paths.
Opening the surviving /dev/hidrawX writes into freed memory. KASAN reports
a use-after-free write from hidraw_open() -> hid_hw_open() -> the
transport's open callback, which takes a spinlock inside the freed object.
A descriptor that carries a PID usage page and no input reports is enough:
hidraw claims the device so hid_hw_start() succeeds, while hid->inputs
stays empty so force-feedback init fails. The other failure returns in
hid_pidff_init_with_quirks() - no output reports, an allocation failure,
pidff_init_fields(), pidff_check_autocenter(), an unusable effect count,
input_ff_create() - all reach the same label.
Stop the device on that path. hid-dr.c and hid-emsff.c, which start the
device with the same HID_CONNECT_DEFAULT & ~HID_CONNECT_FF mask, already do
this. The two earlier gotos must keep returning without hid_hw_stop(),
since neither has a started device, so give the path that fails after the
start its own label.

HID: mcp2221: clear rxbuf after I2C/SMBus transfer completes
mcp_i2c_smbus_read() stores the caller-supplied buffer pointer in
mcp->rxbuf for the duration of a transfer but never clears it when the
transfer finishes or times out. Once the caller frees or reuses the
buffer, mcp->rxbuf becomes a dangling pointer. A delayed or spurious
MCP2221_I2C_GET_DATA report can then drive mcp2221_raw_event() to
memcpy device data into the freed memory, causing a write
use-after-free.
Route all return paths through a single exit point that clears
mcp->rxbuf and mcp->rxbuf_size, so that the existing !mcp->rxbuf guard
in the raw_event handler can reject any report arriving after the
transfer has ended. |
