Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: State corruption has been prevented in fpurestoresig. The non-compacted slowpath uses copyfromuser to copy the entire user buffer into the kernel buffer, verbatim. This means that the kernel buffer may now contain entire...

CVE-2026-64053

A flaw was found in the Linux kernel's block integrity subsystem. Incorrect handling of bio integrity vector counts in the biointegritycopyuser function can lead to an out-of-bounds read during write operations. This vulnerability may allow a local attacker to cause a denial of service or...

CVE-2026-64053

In the Linux kernel, the following vulnerability has been resolved: block: don't overwrite bipvcnt in biointegritycopyuser biointegrityaddpage already sets bipvcnt to 1 for the bounce segment. Overwriting it with nrvecs breaks bipvcnt = bipmaxvcnt on WRITE bipmaxvcnt is 1, so the gap-merge checks...

CVE-2026-43073

A flaw was found in the Linux kernel. The copyusernocache function had a misleading name, which led to its incorrect use by certain kernel components drivers. These drivers performed kernel memory copies without properly considering the function's exception handling mechanisms. This improper usag...

CVE-2026-43073

CVE-2026-43073 stems from a misnamed x86-64 kernel routine __copy_user_nocache(), a non-temporal destination copy with exception handling that is not actually a pure user-kernel copy and has complex alignment behavior. The fix renames the function and normalizes the prototype so callers perform p...
