Google: sys-kernel/csql-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.104.3

high Tenable Cloud Security Plugin ID 467745

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: fs: udf: fix OOB read in
lengthAllocDescs handling When parsing Allocation Extent Descriptor, lengthAllocDescs comes from on-disk
data and must be validated against the block size. Crafted or corrupted images may set lengthAllocDescs so
that the total descriptor length (sizeof(allocExtDesc) + lengthAllocDescs) exceeds the buffer, leading
udf_update_tag() to call crc_itu_t() on out-of-bounds memory and trigger a KASAN use-after-free read. BUG:
