CVE-2025-38013: wifi: mac80211: Set n_channels after allocating struct cfg80211_scan_request

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 07c737d9ab02c07b562aefcca16aa95077368e24, 82bbe02b2500ef0a62053fe2eb84773fe31c5a0a, e3192e999a0d05ea0ba2c59c09afaf0b8ee70b81.

Low priority for now. Upgrade to Linux Linux 07c737d9ab02c07b562aefcca16aa95077368e24, 82bbe02b2500ef0a62053fe2eb84773fe31c5a0a, e3192e999a0d05ea0ba2c59c09afaf0b8ee70b81 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: Set n_channels after allocating struct cfg80211_scan_request Make sure that n_channels is set after allocating the struct cfg80211_registered_device::int_scan_req member. Seen with syzkaller: UBSAN: array-index-out-of-bounds in net/mac80211/scan.c:1208:5 index 0 is out of range for type 'struct ieee80211_channel *[] __counted_by(n_channels)' (aka 'struct ieee80211_channel *[]') This was missed in the initial conversions because I failed to locate the allocation likely due to the "sizeof(void *)" not matching the "channels" array type.
