{"id":"AZL-88779","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:\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().","modified":"2026-08-28T17:48:09.774722151Z","published":"2026-05-27T14:17:30Z","upstream":["CVE-2026-46089"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46089"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88779.json"}}],"schema_version":"1.9.0"}
