CVE-2026-89573 dm array: reject an array block whose value size is not the caller's

In the Linux kernel, the following vulnerability has been resolved: dm array: reject an array block whose value size is not the caller's arrayblockcheck can only compare the header against itself, so a block with valuesize 4 and maxentries 1018 is internally consistent and passes. dm-cache keeps...

CVE-2026-89573

CVE-2026-89573 affects the dm-array component of the Linux kernel , used by dm-cache . The root cause is a value-size mismatch between dm-cache's two arrays (8-byte mappings and 4-byte hints). Because array_block_check() only validates a block against its own header, a crafted superblock can poin...
