Description
A flaw was found in the Linux kernel's cryptographic acceleration (qat) component. This vulnerability occurs because certain functions iterate over a critical data structure without proper synchronization. If another operation modifies this structure concurrently, it can lead to data corruption or a use-after-free error. This could potentially allow an attacker to cause system instability, leading to a denial of service, or in some cases, execute unauthorized code.
