CVE-2026-23130 — Linux Linux Kernel security vulnerability

Medium CVSS 5.5

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix dead lock while flushing management frames Commit [1] converted the management transmission work item into a wiphy work. Since a wiphy work can only run under wiphy lock protection, a race condition happens in below scenario: 1. a management frame is queued for transmission. 2. ath12k_mac_op_flush() gets called to flush pending frames associated with the hardware (i.e, vif being NULL). Then in ath12k_mac_flush() the process waits for the transmission done. 3. Since wiphy lock has been taken by the flush process, the transmission work item has no chance to run, hence the dead lock. >From user view, this dead lock results in below issue: wlp8s0: authenticate with xxxxxx (local address=xxxxxx) wlp8s0: send auth to xxxxxx (try 1/3) wlp8s0: authenticate with xxxxxx (local address=xxxxxx) wlp8s0: send auth to xxxxxx (try 1/3) wlp8s0: authenticated wlp8s0: associate with xxxxxx (try 1/3) wlp8s0: aborting association with xxxxxx by local choice (Reason: 3=DEAUTH_LEAVING) ath12k_pci 0000:08:00.0: failed to flush mgmt transmit queue, mgmt pkts pending 1 The dead lock can be avoided by invoking wiphy_work_f…

Matched remediation archetype

Race condition, TOCTOU, and lifecycle synchronization

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map concurrent actors, shared state, lock boundaries, signals, callbacks, retries, and check-then-use sequences in the affected path.
  • Determine whether untrusted users can influence timing, object names, filesystem state, or repeated state transitions.
  • Identify clustered and multi-process behavior that repository-local tests may not represent.

Remediate safely

  • Make the sensitive state transition atomic or protect it with a consistently ordered synchronization primitive.
  • Perform authorization and invariant checks on the same authoritative object and transaction used for the operation.
  • Use unique private resources, safe ownership transfer, and idempotent operations; add deterministic concurrency regression tests.
