CVE-2025-38601: wifi: ath11k: clear initialized flag for deinit-ed srng lists

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.25% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0ebb5fe494501c19f31270008b26ab95201af6fd, 16872194c80f2724472fc207991712895ac8a230, 3a6daae987a829534636fd85ed6f84d5f0ad7fa4; azl3 kernel 6.6.96.2-2 on Azure Linux 3.0 6.6.104.2-1.
  • Severity is disputed: the assigning authority (CNA) scores it 8.8, NVD 5.5.

Low priority for now. Upgrade to Linux Linux 0ebb5fe494501c19f31270008b26ab95201af6fd, 16872194c80f2724472fc207991712895ac8a230, 3a6daae987a829534636fd85ed6f84d5f0ad7fa4; azl3 kernel 6.6.96.2-2 on Azure Linux 3.0 6.6.104.2-1 or later.

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: clear initialized flag for deinit-ed srng lists In a number of cases we see kernel panics on resume due to ath11k kernel page fault, which happens under the following circumstances: 1) First ath11k_hal_dump_srng_stats() call Last interrupt received for each group: ath11k_pci 0000:01:00.0: group_id 0 22511ms before ath11k_pci 0000:01:00.0: group_id 1 14440788ms before [..] ath11k_pci 0000:01:00.0: failed to receive control response completion, polling.. ath11k_pci 0000:01:00.0: Service connect timeout ath11k_pci 0000:01:00.0: failed to connect to HTT: -110 ath11k_pci 0000:01:00.0: failed to start core: -110 ath11k_pci 0000:01:00.0: firmware crashed: MHI_CB_EE_RDDM ath11k_pci 0000:01:00.0: already resetting count 2 ath11k_pci 0000:01:00.0: failed to wait wlan mode request (mode 4): -110 ath11k_pci 0000:01:00.0: qmi failed to send wlan mode off: -110 ath11k_pci 0000:01:00.0: failed to reconfigure driver on crash recovery [..] 2) At this point reconfiguration fails (we have 2 resets) and ath11k_core_reconfigure_on_crash() calls ath11k_hal_srng_deinit() which destroys srng lists.
