CVE-2026-53369 udf: reject descriptors with oversized CRC length

In the Linux kernel, the following vulnerability has been resolved: udf: reject descriptors with oversized CRC length udfreadtagged skips CRC verification when descCRCLength + sizeofstruct tag exceeds the block size. A crafted UDF image can set descCRCLength to an oversized value to bypass CRC...

CVE-2026-53369

CVE-2026-53369 affects the Linux kernel UDF handling. The vulnerability stems from udf_read_tagged() not rejecting descriptors when descCRCLength + sizeof(struct tag) exceeds the block size, allowing a crafted UDF image to set an oversized CRC length and bypass CRC validation. As a result, a desc...
