CVE-2026-64322

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. The udfloadsparablemap function incorrectly validates the length of the sparing table, treating it as a byte count instead of an entry count. This allows a local attacker, by providing a specially crafted UDF image, to...

CVE-2026-64322

Mode C: Normal. The CVE-2026-64322 issue affects the Linux kernel UDF handling of sparing tables. The problem is that udf_load_sparable_map() validated reallocationTableLen as a byte count, while code walks the sparing table as an array of 8-byte entries, leading to potential out-of-bounds reads ...
