CVE-2026-64323

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. A local attacker could craft a malicious UDF image with a specially formed Virtual Allocation Table VAT header. When this image is mounted, the kernel fails to properly validate the VAT header length against the VAT inod...

CVE-2026-64324

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. The udffreeblocks function fails to properly validate free block extents against the partition length. This allows a local, unprivileged user to create a specially crafted UDF filesystem that, when a file on it is...

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 ...
