CVE-2023-52595: wifi: rt2x00: restart beacon queue when hardware reset

In the Linux kernel, the following vulnerability has been resolved: wifi: rt2x00: restart beacon queue when hardware reset When a hardware reset is triggered, all registers are reset, so all queues are forced to stop in hardware interface. However, mac80211 will not automatically stop the queue. If we don't manually stop the beacon queue, the queue will be deadlocked and unable to start again. This patch fixes the issue where Apple devices cannot connect to the AP after calling ieee80211_restart_hw().

Security readout for executives and security teams

Plain-English summary

CVE-2023-52595 is a Linux kernel Wi-Fi driver reliability issue. In rt2x00-based access point use, a hardware reset can leave the beacon queue stuck, causing client connection failures. The public sources describe an availability/connectivity problem, not data theft, code execution, or privilege escalation.

Executive priority

Handle through normal kernel maintenance unless affected devices provide important Wi-Fi service. Escalate if business operations depend on Linux rt2x00 access points and users report connection failures after resets.

Technical view

The Linux rt2x00 Wi-Fi code failed to restart or stop the beacon queue correctly around ieee80211_restart_hw(). Because hardware reset clears registers and stops queues while mac80211 does not automatically stop the beacon queue, the queue can deadlock and not resume.

Likely exposure

Exposure appears limited to Linux systems using affected kernels with rt2x00 Wi-Fi hardware, especially where the device operates as an access point and experiences hardware restart/reset conditions. Kernel vendor backports may change exact exposure.

Exploitation context

The bundle does not show CISA KEV listing, public exploitation, exploit code, or a security boundary bypass. The documented impact is that Apple devices may fail to connect to an affected Linux access point after hardware restart.

Researcher notes

The evidence is narrow: a kernel driver queue-state bug with stable commits and a Debian LTS advisory. No CVSS, CWE, or exploit details are provided. Validate branch impact through vendor kernel changelogs before broad risk claims.

Mitigation direction

  • Update to a kernel containing the referenced stable fixes.
  • Check Linux distribution advisories for backported kernel packages.
  • Prioritize affected Wi-Fi access points using rt2x00 hardware.
  • Monitor vendor guidance if exact branch status is unclear.

Validation and detection

  • Inventory Linux systems using rt2x00 wireless drivers.
  • Confirm running kernel package includes the stable fix or distribution backport.
  • Review access point logs for post-reset client association failures.
  • Test client reconnection after controlled hardware restart in a lab.
