kernel: wifi: cfg80211: advance loop vars in cfg80211_merge_profile()

A flaw was found in the Linux kernel's cfg80211 Wi-Fi subsystem. A remote attacker, by sending a specially-crafted malicious Wi-Fi beacon, could exploit a vulnerability in the cfg80211mergeprofile function. This flaw causes the kernel to spend an excessive amount of processing time, leading to a...

The vulnerability of the cfg80211_merge_profile() function in the net/wireless/scan.c module of the Linux operating system’s wireless communication support allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the cfg80211mergeprofile function in the net/wireless/scan.c module related to Linux’s wireless communication support is associated with the execution of a loop with an unreachable exit condition an “infinite loop”. Exploiting this vulnerability could allow an attacker to...
