CWE-683  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 6.12.114, 6.18.7 or higher.

Overview

Affected versions of this package are vulnerable to Incorrect Order of Operations in Memory due to misalignment in the virtnet_info structure, specifically involving the rss_trailer.hash_key_data and rss_hash_key_data members. An attacker can cause the device to receive a shifted RSS key, resulting in the last byte being omitted and a potentially uninitialized byte being added at the beginning, by leveraging this misalignment.

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
