No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: hold dev->mt76.mutex while disabling tx worker in SER
mt7996_mac_reset_work() parked the tx worker and disabled the RX/TX NAPIs
before taking dev->mt76.mutex. mt76_worker_disable()/_enable() are plain
kthread park/unpark, not refcounted, and __mt76_set_channel() toggles the
same worker and the MT76_RESET bit under the mutex. An L1 SER racing a
channel switch could therefore have the worker unparked and MT76_RESET
cleared while the reset path resets the DMA rings, corrupting descriptors
or tokens. Take the mutex before disabling the worker, as mt7915 does.
CISA SSVCTrack at low or medium mission impact; Track or Attend at high (mission-essential systems).
No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.
Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
