CVE-2026-98447

The Linux kernel contains a vulnerability in the xfs filesystem where the inode btree root formatting methods perform a wild memcpy access . The root cause is that these methods copy too many bytes because there is only one set of keys in node blocks instead of two, leading to memory corruption o...

CVE-2026-80537

A flaw was found in the Linux kernel's XFS filesystem. An off-by-one error in the rtrefcount btree root level validation allows a local attacker to craft a malicious XFS image. When this image is mounted, it can lead to a slab-out-of-bounds write, causing a kernel panic and a denial of service Do...
