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...

CVE-2026-89576

In the Linux kernel 's dm-era (device mapper era) target, metadata_take_snap() can permanently leak a metadata block on each failed snapshot operation. When dm_tm_shadow_block() allocates a new shadow block for the metadata snapshot, a subsequent failure in dm_sm_inc_block() for either writeset_t...

CVE-2026-89574

CVE-2026-89574 is a vulnerability in the Linux kernel's device mapper (dm) array component. The root cause is insufficient validation of array block headers during read operations: array_block_check() only verifies blocknr and csum, while element_at() performs unguarded pointer arithmetic driven ...

CVE-2026-89573

A local out-of-bounds read in the Linux kernel's device mapper (dm) array component allows memory corruption via crafted metadata . The root cause is that array_block_check() only validates a block's header against itself, so a 4-byte value_size block with max_entries 1018 passes as internally co...
