 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4794-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb September 24, 2026 https://wiki.debian.org/LTS

 Package : redis Version : 5:7.0.15-1~deb12u10 CVE ID : CVE-2026-81934 CVE-2026-92925 Debian Bug : 1147423 1148265

 It was discovered that there were two vulnerabilities in the Redis key/value database.

 CVE-2026-81934

 CVE-2026-81934: Prevent a use-after-free vulnerability in the handling of pending TLS data. A remote, unauthenticated attacker may have been able to execute arbitrary commands with the privileges of the Redis server.

 CVE-2026-92925

 Prevent an out-of-bounds vulnerability in the handling of cluster ping extensions. This could have allowed a remote attacker to craft a malicious packet, leading to an out-of-bounds read when the packet's payload was processed.

 For Debian 12 bookworm, these problems have been fixed in version 5:7.0.15-1~deb12u10.

 We recommend that you upgrade your redis packages.
