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...

CVE-2026-89577

CVE-2026-89577 affects the Linux kernel device-mapper subsystem, specifically dm-io and dm-raid1 . The root cause is that the error codes BLK_STS_NOTSUPP and BLK_STS_INVAL were incorrectly treated as retryable errors, causing a leg failure on dm-raid1 when they should not. The fix introduces two ...
