Linux Kernel Hwtstamp Lock Vulnerability

The Linux kernel's hwtstamp feature allows for timestamping of packets in network devices. The vulnerability affects the way this feature is implemented, allowing an attacker to execute arbitrary code on the system by manipulating the hwtstamp values.

Specific version info not stated in the advisory.

To fix this vulnerability, apply the patch from the Linux kernel stable tree: https://git.kernel.org/stable/c/2d92fa0cdc02291de57f72170e8b60cef0cf5372. Alternatively, upgrade to a newer Linux kernel version that includes the patched code.

Immediate mitigations:

• Restrict network access to your system
• Monitor for suspicious activity related to hwtstamp values

• Patch
• Patch
