Overview

Affected versions of this package are vulnerable to Out-of-Bounds in the ip_vs_nat_icmp process. An attacker can corrupt adjacent kernel memory and potentially hijack control flow by racing to modify the embedded IPv4 ihl field in packet fragments during IPVS ICMP NAT handling, leading to out-of-bounds writes beyond the validated region. This is only exploitable if the attacker has local access with the ability to inject and modify packets while IPVS NAT mode is enabled.

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
