| 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. |

| 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. |
| Unauthenticated Insecure Direct Object References (IDOR) in VikRentCar <= 1.4.5 versions. |
| 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. |
| 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] |
| Unauthenticated Path Traversal in FastDup <= 2.7.2 versions. |
| OpenClaw before 2026.5.18 contains a policy enforcement vulnerability in system.run safe-bin allowlist validation that allows shell expansion to modify command interpretation on POSIX nodes. Authenticated operators can exploit shell metacharacters in approved commands to read unintended node-local files and expose sensitive configuration data. |
| OpenClaw before 2026.4.29 contains an authorization bypass vulnerability in the QQBot streaming command that allows authenticated senders to mutate configuration without explicit allowFrom restrictions. Attackers can modify QQBot streaming configuration outside intended admin policy by reaching the affected command without non-wildcard allowlist entry requirements. |
| unbounded_spsc is an "unbounded" extension of bounded_spsc_queue. In versions 0.2.0 and prior, sender::send pointer-as-value transmute causes OOB read and fake-Arc drop under TX/RX race. At time of publication, there are no publicly available patches. |
| A flaw was found in virtio-win. A low-integrity process can issue an IOCTL request to viosock.sys!VIOSockSelect with a maliciously crafted request that causes an integer overflow. This allows the process to circumvent bounds checking, resulting in a heap overflow in the NonPagedPool kernel heap. The flaw could be exploited to escalate privileges on Windows systems running this driver. |
| OpenStack Ironic before 35.0.2 allows Boot Script Injection of an iPXE script if the attacker can set node.driver_info or node.instance_info. |
| Unauthenticated Cross Site Scripting (XSS) in Product Filter Widget for Elementor <= 1.0.6 versions. |
| Unauthenticated Broken Authentication in Simple Cloudflare Turnstile <= 1.38.0 versions. |
