CVE-2025-39957

HIGH

Linux Kernel 6.4-6.6.107, 6.7-6.12.48, 6.13-6.16.8 DoS via S1G Capability Buffer Validation

Title source: llm

Description

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: increase scan_ies_len for S1G Currently the S1G capability element is not taken into account for the scan_ies_len, which leads to a buffer length validation failure in ieee80211_prep_hw_scan() and subsequent WARN in __ieee80211_start_scan(). This prevents hw scanning from functioning. To fix ensure we accommodate for the S1G capability length.
