Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a race condition in the
skb queue empty() function, where the receive queues are protected by their respective spin-lock, not the socket lock. This could lead to skb peek() unexpectedly returning NULL or a pointer to an already dequeued socket buffer. The vulnerability is also associated with the reuse of previously freed memory due to concurrent access to a resource, which could allow an attacker to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
