CVE-2024-47738

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.58

Description A vulnerability in the Linux kernel has been resolved, related to the wifi: mac80211 component. The issue involved the incorrect use of a rate mask for offchannel TX, which could lead to a no supported rate warning. The cause of the issue was identified as commit 9df66d5b9f45, and the fix involves ignoring incorrect settings to avoid this warning. The change is similar to the one made for SCAN TX.

Recommendations Update to Linux kernel version 6.6.58 or later to resolve the issue. As a temporary workaround, consider disabling the use of rate masks for offchannel TX until a patch is available. Restrict access to the wifi: mac80211 component to minimize the risk of exploitation. Avoid using incorrect settings that could lead to a no supported rate warning until the issue is resolved.
