CVE-2026-89720

A flaw was found in the Linux kernel's Unsorted Block Image File System UBIFS. An incorrect bounds check in the ubifssbverifysignature function allows a crafted signed UBIFS image to declare a signature length larger than its actual size. This can lead to an out-of-bounds read when processing the...
