mm/huge_memory: fix NULL pointer deference when splitting folio
Commit c010d47f107f ("mm: thp: split huge page to any lower order pages")
introduced an early check on the folio's order via mapping->flags before
proceeding with the split work.
This check introduced a bug: for shmem folios in the swap cache and
truncated folios, the mapping pointer can be NULL. Accessing
mapping->flags in this state leads directly to a NULL pointer dereference.
This commit fixes the issue by moving the check for mapping != NULL before
any attempt to access mapping->flags. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/fpu: Fix false-positive kmsan report in fpu_vstl()
A false-positive kmsan report is detected when running ping command.
An inline assembly instruction 'vstl' can write varied amount of bytes
depending on value of 'index' argument. If 'index' > 0, 'vstl' writes
at least 2 bytes.
clang generates kmsan write helper call depending on inline assembly
constraints. Constraints are evaluated compile-time, but value of
'index' argument is known only at runtime.
clang currently generates call to __msan_instrument_asm_store with 1 byte
as size. Manually call kmsan function to indicate correct amount of bytes
written and fix false-positive report.
This change fixes following kmsan reports:

---truncated--- |
| In the Linux kernel, the following vulnerability has been resolved:
fs/namespace: fix reference leak in grab_requested_mnt_ns
lookup_mnt_ns() already takes a reference on mnt_ns.
grab_requested_mnt_ns() doesn't need to take an extra reference. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI/AER: Fix NULL pointer access by aer_info
The kzalloc(GFP_KERNEL) may return NULL, so all accesses to aer_info->xxx
will result in kernel panic. Fix it. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: thead: th1520-ap: set all AXI clocks to CLK_IS_CRITICAL
The AXI crossbar of TH1520 has no proper timeout handling, which means
gating AXI clocks can easily lead to bus timeout and thus system hang.
Set all AXI clock gates to CLK_IS_CRITICAL. All these clock gates are
ungated by default on system reset.
In addition, convert all current CLK_IGNORE_UNUSED usage to
CLK_IS_CRITICAL to prevent unwanted clock gating. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: most: remove broken i2c driver
The MOST I2C driver has been completely broken for five years without
anyone noticing so remove the driver from staging.
Specifically, commit 723de0f9171e ("staging: most: remove device from
interface structure") started requiring drivers to set the interface
device pointer before registration, but the I2C driver was never updated
which results in a NULL pointer dereference if anyone ever tries to
probe it. |
| Stored cross-site scripting (XSS) vulnerability in desknet's NEO V9.0R2.0 and earlier allow execution of arbitrary JavaScript in a user’s web browser. |
| In the Linux kernel, the following vulnerability has been resolved:
iavf: Implement settime64 with -EOPNOTSUPP
ptp_clock_settime() assumes every ptp_clock has implemented settime64().
Stub it with -EOPNOTSUPP to prevent a NULL dereference.
The fix is similar to commit 329d050bbe63 ("gve: Implement settime64
with -EOPNOTSUPP"). |
| In the Linux kernel, the following vulnerability has been resolved:
rtc: amlogic-a4: fix double free caused by devm
The clock obtained via devm_clk_get_enabled() is automatically managed
by devres and will be disabled and freed on driver detach. Manually
calling clk_disable_unprepare() in error path and remove function
causes double free.
Remove the redundant clk_disable_unprepare() calls from the probe
error path and aml_rtc_remove(), allowing the devm framework to
automatically manage the clock lifecycle. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: starfive - Correctly handle return of sg_nents_for_len
The return value of sg_nents_for_len was assigned to an unsigned long
in starfive_hash_digest, causing negative error codes to be converted
to large positive integers.
Add error checking for sg_nents_for_len and return immediately on
failure to prevent potential buffer overflows. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc()
If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then
it results in an out of bounds access.
The code checks for invalid values, but doesn't set the error code. Return
-EINVAL in that case, instead of returning success. |
| In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add()
In mt7615_mcu_wtbl_sta_add(), an skb sskb is allocated. If the
subsequent call to mt76_connac_mcu_alloc_wtbl_req() fails, the function
returns an error without freeing sskb, leading to a memory leak.
Fix this by calling dev_kfree_skb() on sskb in the error handling path
to ensure it is properly released. |
| On affected platforms running Arista EOS with OSPFv3 configured, a specially crafted packet can cause the OSFPv3 process to have high CPU utilization which may result in the OSFPv3 process being restarted. This may cause disruption in the OSFPv3 routes on the switch.
This issue was discovered internally by Arista and is not aware of any malicious uses of this issue in customer networks. |
| The FlexTable WordPress plugin before 3.19.2 does not sanitise and escape the imported links from Google Sheet cells, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup). |
| PaperCut Print Deploy is an optional component that integrates with PaperCut NG/MF which simplifies printer deployment and management. When the component is deployed to an environment, the customer has an option to configure the system to use a self-signed certificate. If the customer does not fully configure the system to leverage the trust database on the clients, it opens up the communication between clients and the server to man-in-the-middle attacks.
It was discovered that certain parts of the documentation related to the configuration of SSL in Print Deploy were lacking, which could potentially contribute to a misconfiguration of the Print Deploy client installation. PaperCut strongly recommends to use valid certificates to secure installations and to follow the updated documentation to ensure the correct SSL configuration. Those who use private CAs and/or self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of their operating system and to the Java key store |
| SummaryUsers with webhook permissions can conduct SSRF via webhooks. If they have permission to view the webhook logs, the (partial) request response is also disclosed
DetailsWhen sending webhooks, the destination is not validated, causing SSRF.
ImpactBypass of firewalls to interact with internal services.
See https://owasp.org/Top10/A10_2021-Server-Side_Request_Forgery_%28SSRF%29/ for more potential impact.
Resources https://cheatsheetseries.owasp.org/cheatsheets/Server_Side_Request_Forgery_Prevention_Cheat_Sheet.html for more information on SSRF and its fix. |
| ImpactThe attacker can validate if a user exists by checking the time login returns. This timing difference can be used to enumerate valid usernames, after which an attacker could attempt brute force attacks.
PatchesThis vulnerability has been patched, implementing a timing-safe form login authenticator that ensures consistent response times regardless of whether a user exists or not.
Technical DetailsThe vulnerability was caused by different response times when:
* A valid username was provided (password hashing occurred)
* An invalid username was provided (no password hashing occurred)
The fix introduces a TimingSafeFormLoginAuthenticator that performs a dummy password hash verification even for non-existent users, ensuring consistent timing.
WorkaroundsNo workarounds are available. Users should upgrade to the patched version.
