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

udf_read_tagged() skips CRC verification when descCRCLength +
sizeof(struct tag) exceeds the block size.  A crafted UDF image can
set descCRCLength to an oversized value to bypass CRC validation
entirely; the descriptor is then accepted based solely on the 8-bit
tag checksum, which is trivially recomputable.

Reject such descriptors instead of silently accepting them.  A
legitimate single-block descriptor should never have a CRC length that
exceeds the block.
