      "title": "zram: do not forget to endio for partial discard requests",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nzram: do not forget to endio for partial discard requests\n\nAs reported by Qu Wenruo and Avinesh Kumar, the following\n\n getconf PAGESIZE\n 65536\n blkdiscard -p 4k /dev/zram0\n\ntakes literally forever to complete.  zram doesn't support partial\ndiscards and just returns immediately w/o doing any discard work in such\ncases.  The problem is that we forget to endio on our way out, so\nblkdiscard sleeps forever in submit_bio_wait().  Fix this by jumping to\nend_bio label, which does bio_endio().",
