Threats tagged 'ghsa-j7w3-jhcq-frvr'

A vulnerability in the Linux kernel's ibmvnic driver could cause a memory leak of socket buffers (skb) during packet transmission. This occurs when internal driver data structures become out of sync, leading to leaked skb references. The leak can disrupt TCP congestion control, potentially causing network timeouts (ETIMEDOUT). The issue is addressed by adding a check to ensure skb pointers are null before assignment, freeing old pointers if not null to prevent leaks and related TCP problems.
