Score 7.8 from GitHub Security Advisory (severity: HIGH) published 2025-09-22.
A fix is available — apply it.
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: fix use-after-free in cmp_bss()
Following bss_free() quirk introduced in commit 776b3580178f ("cfg80211: track hidden SSID networks properly"), adjust cfg80211_update_known_bss() to free the last beacon frame elements only if they're not shared via the corresponding 'hidden_beacon_bss' pointer.
EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).
