CVE-2026-89575

A flaw was found in the Linux kernel's device mapper dm-raid1 component. This vulnerability occurs in the buildconstructorstring function, where insufficient space is reserved for a NUL-terminator when formatting a string with sprintf. This oversight can lead to a buffer overflow, potentially...

CVE-2026-89575

In the Linux kernel, the following vulnerability has been resolved: dm raid1: reserve space for NUL-terminator in buildconstructorstring Reserve space for the termination NUL after the maximum 20 decimal digits of a long long value to avoid buffer overflow in sprintf...

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 ...

EUVD-2026-76489

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...
