Description

A flaw was found in the Linux kernel's Marvell Libertas Wi-Fi driver. This vulnerability, a use-after-free, occurs because the system does not properly synchronize the freeing of memory with ongoing timer operations. If a timer attempts to access resources after they have been released, it can lead to system instability or crashes. In some scenarios, this type of flaw could potentially be exploited by an attacker to execute unauthorized code.
