CVE-2026-66373  (opens in a new tab)
CWE-415  (opens in a new tab)

How to fix?

Upgrade SLES:15.6 redis to version 7.2.4-150600.3.27.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream redis package and not the redis package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

Redis before 8.8.0, in the unusual case where an authenticated attacker can execute RESTORE, allows remote code execution via a RESTORE payload where the same NACK (pending entry) is referenced by more than one consumer, because deleting both consumers via XGROUP DELCONSUMER leads to a double free. NOTE: this issue exists because of an incomplete fix for CVE-2026-25243.
