Description
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: sme: cap SSID length in __cfg80211_connect_result() If the ssid->datalen is more than IEEE80211_MAX_SSID_LEN (32) it would lead to memory corruption so add some bounds checking.

Executive Summary

This vulnerability in the Linux kernel's wifi component (cfg80211) occurs when the SSID length exceeds the maximum allowed length of 32 bytes (IEEE80211_MAX_SSID_LEN). Without proper bounds checking, this can lead to memory corruption in the __cfg80211_connect_result() function.

Impact Analysis

The memory corruption caused by an SSID length exceeding the maximum limit could potentially lead to system instability, crashes, or exploitation by attackers to execute arbitrary code or cause denial of service.
