Package        : redis
Version        : 5:7.0.15-1~deb12u8
CVE ID         : CVE-2026-23631 CVE-2026-25243

It was discovered that there were two issues in Redis, the in-memory
key/value database:

CVE-2026-23631

    An authenticated attacker could have exploited the master-replica
    synchronization mechanism to trigger a use-after-free on replicas
    where "replica-read-only" is disabled (or could be disabled),
    which may have led to remote code execution. Installations that
    prevent users from executing Lua scripts were unaffected.

CVE-2026-25243

    The RESTORE command did not properly validate serialized values.
    An authenticated attacker with permission to execute RESTORE
    could have suppled a crafted serialized payload that triggers
    invalid memory access and this could have led to remote code
    execution.

For Debian 12 bookworm, these problems have been fixed in version
5:7.0.15-1~deb12u8.

We recommend that you upgrade your redis packages.
