CVE-2026-9728 TOCTOU race in mbox_send syscall verifier allows userspace to leak kernel memory

The userspace syscall verifier zvrfymboxsend in drivers/mbox/mboxhandlers.c validated the nested msg-data/msg-size fields by reading them directly out of live userspace memory, and then forwarded the original, still-mutable userspace struct mboxmsg pointer to zimplmboxsend and the underlying...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fixed the loop termination condition in gssfreeintokenpages. The intoken-pages array is not NULL-terminated. This results in the following KASAN issue: KASAN: Potential wild-memory-access in the range...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: bound DeleteIndexEntryAllocation memmove length In the DeleteIndexEntryAllocation case in doaction, e-size comes from an INDEXBUFFER entry stored in memory. When e-size causes e + e-size to point past hdr + hdr-used,...

Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel through version 5.11.x. The kernel/bpf/verifier.c file contains unwanted out-of-bounds speculation during pointer arithmetic operations, which allows for side-channel attacks that circumvent Spectre mitigations and extract sensitive information from kern...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dm-integrity: Fix for leaking uninitialized kernel memory. If the hash size is less than the device’s tuple size, dm-integrity is supposed to zero the remaining space. There was a bug in the code where this zeroing operation didn...
