CVE-2024-42114

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.9.0-rc7-syzkaller-gfda5695d692c

Description The vulnerability is related to the wifi component in the Linux kernel, specifically with the cfg80211 module. It allows an attacker to trigger softlockups by setting the NL80211 ATTR TXQ QUANTUM value to 2^31. This issue is similar to a previously fixed problem in the sch fq module. The vulnerability can cause a denial-of-service (DoS) condition, where the system becomes unresponsive.

Recommendations To resolve this issue, update the Linux kernel to a version that includes the fix for this vulnerability. If an update is not available, consider temporarily disabling the wifi functionality or restricting access to the vulnerable module to minimize the risk of exploitation.
