valkey: Valkey: Remote code execution via use-after-free in stream deserialization

A flaw was found in Valkey, a distributed key-value database. A remote attacker could exploit a use-after-free vulnerability in the RESTORE command. This occurs when a malformed data stream is processed during stream deserialization, causing a shared resource to be improperly managed. If...

redis: Redis: Remote Code Execution via specially crafted RESTORE payload

A flaw was found in Redis. An authenticated attacker, in an unusual configuration where they can execute the RESTORE command, could exploit a double free vulnerability. This occurs when a specially crafted RESTORE payload references the same NACK pending entry by multiple consumers, and both...

Astra Linux – Vulnerability in Redis

Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can provide a crafted serialized payload that triggers invalid memory access and may...

ALSA-2026:64807 Important: valkey security, bug fix, and enhancement update

Valkey 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. You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing to a list; computing s...
