🚨 CVE-2026-46058
In the Linux kernel, the following vulnerability has been resolved:

media: amphion: Fix race between m2m job_abort and device_run

Fix kernel panic caused by race condition where v4l2_m2m_ctx_release()
frees m2m_ctx while v4l2_m2m_try_run() is about to call device_run
with the same context.

Race sequence:
v4l2_m2m_try_run(): v4l2_m2m_ctx_release():
lock/unlock v4l2_m2m_cancel_job()
job_abort()
v4l2_m2m_job_finish()
kfree(m2m_ctx) <- frees ctx
device_run() <- use-after-free crash at 0x538

Crash trace:
Unable to handle kernel read from unreadable memory at virtual address
0000000000000538
v4l2_m2m_try_run+0x78/0x138
v4l2_m2m_device_run_work+0x14/0x20

The amphion vpu driver does not rely on the m2m framework's device_run
callback to perform encode/decode operations.

Fix the race by preventing m2m framework job scheduling entirely:
- Add job_ready callback returning 0 (no jobs ready for m2m framework)
- Remove job_abort callback to avoid the race condition

🚨 CVE-2026-46059
In the Linux kernel, the following vulnerability has been resolved:

KVM: nSVM: Always use NextRIP as vmcb02's NextRIP after first L2 VMRUN

For guests with NRIPS disabled, L1 does not provide NextRIP when running
an L2 with an injected soft interrupt, instead it advances the current RIP
before running it. KVM uses the current RIP as the NextRIP in vmcb02 to
emulate a CPU without NRIPS.

However, after L2 runs the first time, NextRIP will be updated by the CPU
and/or KVM, and the current RIP is no longer the correct value to use in
vmcb02. Hence, after save/restore, use the current RIP if and only if a
nested run is pending, otherwise use NextRIP. Give soft_int_next_rip the
same treatment, as it's the same logic, just for a narrower use case.

[sean: give soft_int_next_rip the same treatment]

🚨 CVE-2026-46060
In the Linux kernel, the following vulnerability has been resolved:

crypto: qat - fix IRQ cleanup on 6xxx probe failure

When adf_dev_up() partially completes and then fails, the IRQ
handlers registered during adf_isr_resource_alloc() are not detached
before the MSI-X vectors are released.

Since the device is enabled with pcim_enable_device(), calling
pci_alloc_irq_vectors() internally registers pcim_msi_release() as a
devres action. On probe failure, devres runs pcim_msi_release() which
calls pci_free_irq_vectors(), tearing down the MSI-X vectors while IRQ
handlers (for example 'qat0-bundle0') are still attached. This causes
remove_proc_entry() warnings:

[ 22.163964] remove_proc_entry: removing non-empty directory 'irq/143', leaking at least 'qat0-bundle0'

Moving the devm_add_action_or_reset() before adf_dev_up() does not solve
the problem since devres runs in LIFO order and pcim_msi_release(),
registered later inside adf_dev_up(), would still fire before
adf_device_down().

Fix by calling adf_dev_down() explicitly when adf_dev_up() fails, to
properly free IRQ handlers before devres releases the MSI-X vectors.

🚨 CVE-2026-46061
In the Linux kernel, the following vulnerability has been resolved:

jbd2: fix deadlock in jbd2_journal_cancel_revoke()

Commit f76d4c28a46a ("fs/jbd2: use sleeping version of
__find_get_block()") changed jbd2_journal_cancel_revoke() to use
__find_get_block_nonatomic() which holds the folio lock instead of
i_private_lock. This breaks the lock ordering (folio -> buffer) and
causes an ABBA deadlock when the filesystem blocksize < pagesize:

T1 T2
ext4_mkdir()
ext4_init_new_dir()
ext4_append()
ext4_getblk()
lock_buffer() <- A
sync_blockdev()
blkdev_writepages()
writeback_iter()
writeback_get_folio()
folio_lock() <- B
ext4_journal_get_create_access()
jbd2_journal_cancel_revoke()
__find_get_block_nonatomic()
folio_lock() <- B
block_write_full_folio()
lock_buffer() <- A

This can occasionally cause generic/013 to hang.

Fix by only calling __find_get_block_nonatomic() when the passed
buffer_head doesn't belong to the bdev, which is the only case that we
need to look up its bdev alias. Otherwise, the lookup is redundant since
the found buffer_head is equal to the one we passed in.

🚨 CVE-2026-46062
In the Linux kernel, the following vulnerability has been resolved:

ntfs3: fix integer overflow in run_unpack() volume boundary check

The volume boundary check `lcn + len > sbi->used.bitmap.nbits` uses raw
addition which can wrap around for large lcn and len values, bypassing
the validation. Use check_add_overflow() as is already done for the
adjacent prev_lcn + dlcn and vcn64 + len checks added by commit
3ac37e100385 ("ntfs3: Fix integer overflow in run_unpack()").

Found by fuzzing with a source-patched harness (LibAFL + QEMU).

🚨 CVE-2026-46063
In the Linux kernel, the following vulnerability has been resolved:

x86/shstk: Prevent deadlock during shstk sigreturn

During sigreturn the shadow stack signal frame is popped. The kernel does
this by reading the shadow stack using normal read accesses. When it can't
assume the memory is shadow stack, it takes extra steps to makes sure it is
reading actual shadow stack memory and not other normal readable memory. It
does this by holding the mmap read lock while doing the access and checking
the flags of the VMA.

Unfortunately that is not safe. If the read of the shadow stack sigframe
hits a page fault, the fault handler will try to recursively grab another
mmap read lock. This normally works ok, but if a writer on another CPU is
also waiting, the second read lock could fail and cause a deadlock.

Fix this by not holding mmap lock during the read access to userspace.

Instead use mmap_lock_speculate_...() to watch for changes between dropping
mmap lock and the userspace access. Retry if anything grabbed an mmap write
lock in between and could have changed the VMA.

These mmap_lock_speculate_...() helpers use mm::mm_lock_seq, which is only
available when PER_VMA_LOCK is configured. So make X86_USER_SHADOW_STACK
depend on it. On x86, PER_VMA_LOCK is a default configuration for SMP
kernels. So drop support for the other configs under the assumption that
the !SMP shadow stack user base does not exist.

Currently there is a check that skips the lookup work when the SSP can be
assumed to be on a shadow stack. While reorganizing the function, remove
the optimization to make the tricky code flows more common, such that
issues like this cannot escape detection for so long.

🚨 CVE-2026-4408
A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service.

🚨 CVE-2026-10611
An authentication bypass vulnerability exists in MISP when LDAP mixed authentication is enabled with OTP enforcement. In deployments configured with LdapAuth.mixedAuth=true and Security.require_otp=true, users authenticated through an authentication plugin, such as LDAP, may have their authenticated session established during the application beforeFilter phase before the normal login flow enforces the OTP challenge.



As a result, an attacker with valid primary authentication credentials could bypass the required OTP step by authenticating through the plugin-backed login flow and then directly accessing another application URL instead of completing the OTP verification page. This allows access to the application as the affected user without providing a valid TOTP, HOTP, or email OTP code.



The issue affects configurations where plugin-based authentication is enabled and OTP is expected to be mandatory. The fix ensures that OTP requirements are checked immediately after plugin authentication and before the user session is established, redirecting users to the appropriate OTP challenge when required.

🚨 CVE-2026-46389
UDS Identity Config builds the Keycloak configuration image (realm, plugins, theme, truststore, JARs) consumed by UDS Core's Identity deployment. In versions 0.11.0 through 0.26.0, a logic error in the `client-kubernetes-secret` Keycloak client authenticator (shipped by `uds-identity-config` and consumed by UDS Core) causes the submitted `client_secret` to be overwritten with the mounted Kubernetes secret before comparison. An attacker who can reach the Keycloak token endpoint and knows a `client_id` using this authenticator can authenticate as that client with any `client_secret` value and obtain OAuth2 tokens scoped to the client's service account. In the case of the `uds-operator` client this token can be used to registry/modify other clients. Version 0.26.1 patches the issue.

🚨 CVE-2026-45409
Internationalized Domain Names in Applications (IDNA) for Python provides support for Internationalized Domain Names in Applications (IDNA) and Unicode IDNA Compatibility Processing. In versions prior to 3.15, payloads such as `"\u0660" * N` or `"\u30fb" * N + "\u6f22"` utilize the `valid_contexto` function prior to length rejection, and for high values of `N` will take a long time to process. This is the same issue as CVE-2024-3651, however the original remediation in 2024 was not a complete fix. A specially crafted argument to the `idna.encode()` function could consume significant resources. This may lead to a denial-of-service. Starting in version 3.14, the function rejects long inputs as soon as practicable prior to any further processing to minimize resource consumption. In version 3.15, this approach was extended to lesser used alternate functions (i.e. per-label conversions and codec support). A workaround is available. Domain names cannot exceed 253 characters in length. If this length limit is enforced prior to passing the domain to the `idna.encode()` function, it should no longer consume significant resources. This is triggered by arbitrarily large inputs that would not occur in normal usage, but may be passed to the library assuming there is no preliminary input validation by the higher-level application.
