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: zram: do not forget to endio for
partial discard requests As reported by Qu Wenruo and Avinesh Kumar, the following getconf PAGESIZE 65536
blkdiscard -p 4k /dev/zram0 takes literally forever to complete. zram doesn't support partial discards and
just returns immediately w/o doing any discard work in such cases. The problem is that we forget to endio
on our way out, so blkdiscard sleeps forever in submit_bio_wait(). Fix this by jumping to end_bio label,
which does bio_endio(). (CVE-2026-46089)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.613.40 or later.
