A flaw was found in the Linux kernel's XFS filesystem. The xfs_attr3_leaf_verify_entry() function fails to validate an attribute entry pointer before accessing its fields. A local attacker could exploit this by crafting a malicious attribute index (nameidx) to cause an out-of-bounds read. This could lead to the disclosure of sensitive information or a denial of service.
