CWE-787  (opens in a new tab)

How to fix?

Overview

Affected versions of this package are vulnerable to Out-of-Bounds through a race condition between ethtool -L and ethtool -S operations in the iavf_get_ethtool_stats process. An attacker can cause out-of-bounds kernel memory writes by manipulating queue configuration and statistics retrieval in rapid succession, potentially leading to memory corruption, privilege escalation, or denial of service.

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
