{"id":"ALSA-2026:64824","summary":"Important: redis security, bug fix, and enhancement update","details":"Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log.  \n\nSecurity Fix(es):  \n\n  * redis: Redis: Remote Code Execution via specially crafted RESTORE payload (CVE-2026-66373)\n  * redis: Redis: Arbitrary code execution via TLS pending-data list use-after-free (CVE-2026-81934)\n\n\nBug Fix(es) and Enhancement(s):  \n\n  * segfault because of Unsupported system page size (jemalloc) (JIRA:AlmaLinux-180910)\n\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n","modified":"2026-09-09T12:00:04.235584621Z","published":"2026-09-08T00:00:00Z","related":["CVE-2026-66373","CVE-2026-81934"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:64824"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-66373"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-81934"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2506985"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2525226"},{"type":"ADVISORY","url":"https://errata.almalinux.org/9/ALSA-2026-64824.html"}],"affected":[{"package":{"name":"redis","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/redis"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.24-1.el9_8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:64824.json"}},{"package":{"name":"redis-devel","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/redis-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.24-1.el9_8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:64824.json"}},{"package":{"name":"redis-doc","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/redis-doc"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.24-1.el9_8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:64824.json"}}],"schema_version":"1.9.0"}
