CVE-2026-23479redis-server use-after-free in unblock client flow may allow remote code execution

redis redis; Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Red Hat Enterprise Linux 9 Publicada: (hace 6 meses)

Descripción

Redis is an in-memory data structure store. In redis-server from 7.2.0 until 8.6.3, the unblock client flow does not handle an error return from `processCommandAndResetClient` when re-executing a blocked command. If a blocked client is evicted during this flow, an authenticated attacker can trigger a use-after-free that may lead to remote code execution. This has been patched in version 8.6.3.

Debilidad (CWE): CWE-416
