Description OSIDB Bzimport 2025-09-19 16:02:12 UTC 
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.
