CVE-2026-74671

CVE-2026-74671 is an out-of-bounds read in the Linux kernel's IMA (Integrity Measurement Architecture) subsystem, specifically in the xattr_verify() function. The root cause is a type mismatch between int and size_t in the digest-length check: sizeof() promotes the entire left-hand expression to ...
