Summary

A use after free vulnerability has been identified in the Linux kernel's ATM networking stack, specifically within the lec_send() operation. This flaw arises when the skb (socket buffer) is freed before its length is saved, resulting in potential memory access violations. It is critical for system administrators to apply updates to prevent exploitation that could lead to unintended behavior or system instability.
