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

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...

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...

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...

CVE-2026-64052

CVE-2026-64052 is a null pointer dereference in the Linux kernel's block layer , specifically in bio_integrity_map_user(). The root cause is that pin_user_pages_fast() can partially succeed (pinning fewer pages than requested), but bio_integrity_map_user() does not handle this case, causing bvec_...
