CVE-2026-63825  (opens in a new tab)
CWE-787  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 6.1.191, 6.6.160, 6.12.114, 6.18.38, 7.1.3 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds through concurrent execution of the inflate_fast function. An attacker can cause arbitrary kernel memory corruption and potentially achieve remote code execution or denial of service by sending crafted IPComp packets to a system with IPComp enabled, triggering decompression on multiple CPUs simultaneously.

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
