CVE-2026-80656

A flaw was found in the Linux kernel's hfsplus filesystem. A local attacker could provide a specially crafted and corrupted HFS+ image. When attempting to mount this image, a malformed btree node size value could lead to the use of an uninitialized value within the kernel. This could result in a...

CVE-2026-80656

CVE-2026-80656 is an uninitialized value vulnerability in the Linux kernel's hfsplus (HFS+) filesystem driver. During mounting of a crafted HFS+ image, a corrupted node_size value of 1 causes an excessively large rec_off argument to be passed to hfs_bnode_read_u16() within hfs_bnode_find(), leavi...
