CVE-2024-36971 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 4.19.316, 5.4.278, 5.10.219, 5.15.161, 6.1.94, 6.6.34, 6.9.4 or higher.
Overview
Affected versions of this package are vulnerable to Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') through a race condition in the __dst_negative_advice process. An attacker can achieve local privilege escalation, arbitrary code execution, and kernel memory disclosure by exploiting concurrent operations on the same UDP socket, leading to use-after-free of kernel objects.
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
