wifi: cfg80211: check A-MSDU format more carefully

published 2024-05-19 2 y ago modified 2026-10-08 31 d ago also EUVD-2024-35655

cvss: 8.1; version 3.1, CNA
cisa kev: Not listed; not in CISA's catalog
epss: 0.3%; EPSS 0.3% chance of exploitation in 30 days, percentile 28%
public exploits: 0; none known

In the Linux kernel, the following vulnerability has been resolved:

If it looks like there's another subframe in the A-MSDU but the header isn't fully there, we can end up reading data out of bounds, only to discard later. Make this a bit more careful and check if the subframe header can even be present.
