Overview

Affected versions of this package are vulnerable to Buffer Overflow in the esp_ssg_unref function. An attacker can gain arbitrary code execution or escalate privileges by exploiting improper reference counting of managed fragment pages, which can lead to freeing memory still in use and subsequent memory corruption. This is only exploitable if the attacker has local privileges, can register buffers with io_uring, and can install or use an existing IPsec Security Association.

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
