CVE-2026-98958: wifi: mt76: account non-AQL frames per peer rather than per link

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 752770d7a58c821c17909c3ca67f9f14ab146a40, 9f28f504650869d41f7b3e98e4bc4547af4d5670, e0f2ae4a7539454ec50c353571779fcda8c0cfcf.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 752770d7a58c821c17909c3ca67f9f14ab146a40, 9f28f504650869d41f7b3e98e4bc4547af4d5670, e0f2ae4a7539454ec50c353571779fcda8c0cfcf or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: account non-AQL frames per peer rather than per link The driver increments wcid->non_aql_packets when a frame goes to the hardware queue. The completion path decrements the counter again. For an MLO peer, the hardware reports the completion on the link that it used for the transmission. This link can differ from the link that the driver queued the frame on. In that case, the increment and the decrement go to different link wcids, and the count drifts upwards until it blocks the station. Keep the count on the wcid of the primary link, like the other peer-wide state.
