CVE-2025-38505 — Linux Linux Kernel security vulnerability

Medium CVSS 5.5

In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: discard erroneous disassoc frames on STA interface When operating in concurrent STA/AP mode with host MLME enabled, the firmware incorrectly sends disassociation frames to the STA interface when clients disconnect from the AP interface. This causes kernel warnings as the STA interface processes disconnect events that don't apply to it: [ 1303.240540] WARNING: CPU: 0 PID: 513 at net/wireless/mlme.c:141 cfg80211_process_disassoc+0x78/0xec [cfg80211] [ 1303.250861] Modules linked in: 8021q garp stp mrp llc rfcomm bnep btnxpuart nls_iso8859_1 nls_cp437 onboard_us [ 1303.327651] CPU: 0 UID: 0 PID: 513 Comm: kworker/u9:2 Not tainted 6.16.0-rc1+ #3 PREEMPT [ 1303.335937] Hardware name: Toradex Verdin AM62 WB on Verdin Development Board (DT) [ 1303.343588] Workqueue: MWIFIEX_RX_WORK_QUEUE mwifiex_rx_work_queue [mwifiex] [ 1303.350856] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 1303.357904] pc : cfg80211_process_disassoc+0x78/0xec [cfg80211] [ 1303.364065] lr : cfg80211_process_disassoc+0x70/0xec [cfg80211] [ 1303.370221] sp : ffff800083053be0 [ 1303.373590] x29: ffff800083053be0 x28…

Matched remediation archetype

General vulnerability remediation

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

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
