CVE-2024-41072: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-41072 affects the Linux kernel's wifi subsystem, specifically in the cfg80211 wireless extension (wext) component. The vulnerability was discovered and disclosed in July 2024, affecting the Linux kernel's wireless networking stack. The issue involves improper validation of channel numbers in the SIOCSIWSCAN functionality (NVD).

The vulnerability exists in the 'cfg80211wextsiwscan()' function where there was insufficient validation of the number of channels passed via 'ioctl(sock, SIOCSIWSCAN, ...)'. The function did not properly check whether the number of channels exceeded IWMAXFREQUENCIES before processing the request (Kernel Commit).

If exploited, this vulnerability could allow an attacker to potentially cause a denial of service condition by passing an invalid number of channels that exceeds the maximum allowed frequencies (Oracle Linux).

The issue has been fixed in multiple Linux kernel versions through a patch that adds an extra validation check. The fix rejects invalid requests with -EINVAL when the number of channels exceeds IWMAXFREQUENCIES. Updates are available for various Linux distributions including Ubuntu 24.04 LTS, 22.04 LTS, and 20.04 LTS (Ubuntu Security).
