Buffer Management Vulnerability in Linux Kernel

CVE-2023-53354

What is CVE-2023-53354?

In the Linux kernel, a flaw in the skb_segment() function occurs when calls to zero copy functions interfere with buffer fragment management. This mismanagement can lead to a kernel NULL pointer dereference, which results in a kernel panic when the system attempts to access a non-existent memory reference. This vulnerability emphasizes the importance of correct buffer handling in network operations and necessitates immediate attention to prevent potential system crashes.
