CVE-2024-42114

A vulnerability was found in the cfg80211 component in the Linux kernel, where a lack of proper range validation applied to the NL80211_ATTR_TXQ_QUANTUM can lead to a scenario where the userspace passes an extremely high value that the kernel is not designed to handle efficiently (ex. 2^31). This can cause soft lockups and system instability.

Red Hat believes this flaw is moderate severity because the privileges necessary to effectively trigger this vulnerability require the user to be able to craft and send a Netlink message with the NL80211_ATTR_TXQ_QUANTUM parameter set to an abnormally high value. The permissions necessary to set this value would require CAP_NET_ADMIN.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
