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().
