CVE-2026-89578 dm-io: clone the source bio instead of copying its biovec

In the Linux kernel, the following vulnerability has been resolved: dm-io: clone the source bio instead of copying its biovec For DMIOBIO requests, doregion built each destination bio by walking the source bio's biovec and re-adding the pages one at a time, tracking the remaining transfer in...

CVE-2026-89578

CVE-2026-89578 affects the Linux kernel's dm-io component. In do_region(), DM_IO_BIO requests rebuilt each destination bio by walking the source bio's biovec and re-adding pages individually, using sector-based accounting . When a misaligned O_DIRECT buffer was split across pages, the vector leng...

In the Linux kernel, the following vulnerability has been resolved: dm-io: report non-retryable errors separatedly The error codes BLKSTSNOTSUPP and BLKSTSINVAL should not cause leg failure on dm-raid1. This patch changes the interface to dm-io, so that it reports two error bitmaps - errorbits an...

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 ...

CVE-2026-89575

CVE-2026-89575 affects the Linux kernel 's device-mapper RAID1 (dm raid1) subsystem. The vulnerability is a buffer overflow in the build_constructor_string() function, where the code fails to reserve space for the NUL-terminator after the maximum 20 decimal digits of a long long value when callin...
