CVE-2026-89525

This vulnerability affects the Linux kernel's UDF 1.50 virtual partition mapping in the function udf_get_pblock_virt15() . The root cause is an off-by-one bounds check : the code rejected only indexes greater than s_num_entries, but valid VAT indexes are strictly below that value. A crafted UDF i...
