CVE-2026-80808

CVE-2026-80808 affects the Linux kernel ext4 filesystem. The bug is in ext4_xattr_block_set() , which retries indefinitely when an mbcache entry selected for reuse has a saturated reference count (≥ EXT4_XATTR_REFCOUNT_MAX , 1024). Normally this invariant holds because the count and MBE_REUSABLE_...

CVE-2026-80806

CVE-2026-80806 is a flaw in the Linux kernel's ext4 filesystem where newly created encrypted files could incorrectly have the DAX (Direct Access) flag enabled when the filesystem is mounted with -o dax=always. The root cause is a timing issue in __ext4_new_inode(): the call to ext4_set_inode_flag...
