Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: Block: Initialize the integrity buffer to zero before writing it to the media. The metadata added by biointegrityprep uses the plain kmalloc function, which results in random kernel memory being written to the media. For PI...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: blk-mq: Ensure that the active queue usage is retained for biointegrityprep. The function blkintegrityunregister may be called if the queue usage counter is not retained for a bio with integrity prepared. This could lead to a...

Linux Distros Unpatched Vulnerability : CVE-2026-89770

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: iomap: don't free integrity payload that doesn't exist fsbiointegrityalloc might not allocat...

CVE-2026-89770

A flaw was found in the iomap component of the Linux kernel. This vulnerability occurs when Protection Information PI verification is disabled on a block device, causing fsbiointegrityalloc to not allocate a bio integrity payload. Subsequently, the iomapbioreadfoliorangesync function attempts to...

CVE-2026-89770

In the Linux kernel, the following vulnerability has been resolved: iomap: don't free integrity payload that doesn't exist fsbiointegrityalloc might not allocate a bio integrity payload if PI verification is disabled on the block device. Check for that case before calling fsbiointegrityfree in...

CVE-2026-89770 iomap: don't free integrity payload that doesn't exist

In the Linux kernel, the following vulnerability has been resolved: iomap: don't free integrity payload that doesn't exist fsbiointegrityalloc might not allocate a bio integrity payload if PI verification is disabled on the block device. Check for that case before calling fsbiointegrityfree in...

CVE-2026-89770

CVE-2026-89770 is a NULL pointer dereference in the Linux kernel's iomap subsystem . When PI (Protection Information) verification is disabled on a block device, fs_bio_integrity_alloc may fail to allocate a bio integrity payload. The function iomap_bio_read_folio_range_sync then calls fs_bio_int...

The vulnerability of the bio_integrity_copy_user() function in the block/bio-integrity.c module, which supports the block-level kernel in the Linux operating system. This vulnerability allows an attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the biointegritycopyuser function in the block/bio-integrity.c module, which supports the block-level kernel in the Linux operating system, is related to the execution of operations outside the buffer boundaries. Exploiting this vulnerability could allow an attacker to...

The vulnerability of the bio_integrity_map_user() function in the block/bio-integrity.c module, which supports the block-level kernel in the Linux operating system, allows a hacker to trigger a service failure.

The vulnerability of the biointegritymapuser function in the block/bio-integrity.c module, which supports the block-level kernel in the Linux operating system, is related to the pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

SUSE CVE-2026-64052

In the Linux kernel, the following vulnerability has been resolved: block: bio-integrity: Fix null-ptr-deref in biointegritymapuser pinuserpagesfast can partially succeed and return the number of pages that were actually pinned. However, the biointegritymapuser does not handle this partial pinnin...

SUSE 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-2026-64053

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-2026-64052

A flaw was found in the Linux kernel's bio-integrity module. The biointegritymapuser function does not correctly handle partially pinned user pages, which can occur when pinuserpagesfast returns fewer pages than requested. This oversight leads to a null-pointer dereference when attempting to acce...
