Summary
CVE-2026-46089 affecting package kernel for versions less than 6.6.141.1-1
Details

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 submitbiowait(). Fix this by jumping to endbio label, which does bioendio().
