Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: udf: reject VAT indexes equal to the
 entry count UDF 1.50 virtual partition mapping uses the VAT as an array of physical block mappings.
 s_num_entries stores the number of entries in that array, not the highest valid index. The valid VAT
 indexes are therefore below s_num_entries. udf_get_pblock_virt15() currently rejects only indexes greater
 than s_num_entries. A crafted image can request index s_num_entries, pass the bounds check, and make the
 kernel read one entry past the allocated VAT table. Change the check to reject block >= s_num_entries, so
 the count is handled as an exclusive upper bound. A crafted UDF image reproduced this on origin/master
 commit 0e35b9b6ec0ffcc5e23cbdec09f5c622ad532b53 with a KASAN slab-out-of-bounds report in
 udf_get_pblock_virt15(). Trail of Bits has a reproducer that triggers kernel panic demonstrating the bug,
 and can share it if needed. (CVE-2026-89525)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
