wifi: mac80211: don't start a ROC while scanning

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 58b806f699052c572dec6cab2c376f884f27e98f, 5dc8ec2f8d1d62914661577c23ec151f5c9734a4, 733f0fde95392ed5f61a4e36aee661ea8d0e8581; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes.

Low priority for now. Upgrade to Linux Linux 58b806f699052c572dec6cab2c376f884f27e98f, 5dc8ec2f8d1d62914661577c23ec151f5c9734a4, 733f0fde95392ed5f61a4e36aee661ea8d0e8581; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't start a ROC while scanning The ROC work can be pending when a scan starts (which requires ROC list to be empty, but that's possible), and then a new ROC can be added to the list and the work will pick it up. Avoid starting that ROC if a scan made it between things, as otherwise we'll hit a warning later: WARNING: net/mac80211/offchannel.c:404 at ieee80211_start_next_roc+0x256/0x2d0 Workqueue: events_unbound cfg80211_wiphy_work Call Trace: __ieee80211_scan_completed+0x4fd/0xe40 net/mac80211/scan.c:537 ieee80211_scan_work+0x472/0x1ff0 net/mac80211/scan.c:1193 cfg80211_wiphy_work+0x410/0x570 net/wireless/core.c:513

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Bug bounty scope

No known public program.

Source: bounty-targets-data (public HackerOne, Bugcrowd, Intigriti, YesWeHack listings).

Technical details

No CVSS vector for this record, so attack conditions can't be derived.

Weakness class (CWE)

Attack context

MITRE CAPEC attack patterns and ATT&CK techniques for this weakness class (CWE). A starting point for detection rules and threat hunting.

MITRE has no CAPEC/ATT&CK mapping for this CWE.
