Overview

Affected versions of this package are vulnerable to Use After Free in the __bpf_rbtree_add process. An attacker can cause use-after-free conditions by invoking resilient lock kfuncs within an rbtree comparison callback, which may allow another CPU to remove and free a node referenced during an in-progress tree walk, leading to the use of freed pointers.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
