Описание

Valkey is a distributed key-value database. Prior to 7.2.14, 8.0.10, 8.1.9, 9.0.5, and 9.1.1, Valkey's RESTORE command accepts a malformed RDB stream payload that assigns one Pending Entry List NACK to multiple consumers during stream consumer-group deserialization, causing a use-after-free when one consumer is deleted while another still references the shared NACK and potentially allowing remote code execution. This issue is fixed in versions 7.2.14, 8.0.10, 8.1.9, 9.0.5, and 9.1.1.

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 successfully exploited, this flaw could lead to remote code execution.

Меры по смягчению последствий

To mitigate this issue, restrict network access to the Valkey instance to only trusted clients and networks. This limits an attacker's ability to send malformed RDB stream payloads to the RESTORE command. Implement firewall rules to block unauthorized access to the Valkey port.
