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

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...
