Memory Leak in Linux Kernel Stream Parser Affects System Stability

CVE-2026-46102

What is CVE-2026-46102?

A vulnerability in the Linux kernel's stream parser allows for a memory leak associated with the 'skb_head' structure when an abort occurs. This issue can lead to exhaustion of system memory as the parser fails to release references to partially assembled messages. The flaw manifests during message assembly timeouts and can be exploited repeatedly without proper cleanup, potentially impacting system stability. A fix has been implemented to free the 'skb_head' and reset parser state, ensuring memory is appropriately managed and preventing resource exhaustion.
