CVE-2026-89578

A flaw was found in the Linux kernel's device mapper I/O dm-io component. When handling DMIOBIO requests, incorrect sector-based accounting for misaligned direct I/O buffers could lead to an infinite loop. This issue can cause I/O operations to hang indefinitely, resulting in a denial of service...

CVE-2026-89578

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...

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 ...

kernel: dm ioctl: prevent potential spectre v1 gadget

A vulnerability was found in the Linux kernel's dm-ioctl interface in the lookupioctl function, which accepts a user-provided cmd value that is used to index the ioctls array directly. This issue could lead to an out-of-bounds access if the CPU speculatively executes the array access before cmd i...
