CVE-2025-38290: wifi: ath12k: fix node corruption in ar->arvifs list

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: 0.24% (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 6285516170f9e2f04b9dbf1e5100e0d7cbac22b4, 6bfe7ae9bbd9734751b853e2d2e1c13e8b46fd2d, 823435bd23108d6f8be89ea2d025c0e2e3769c51; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1.
  • Severity is disputed: the assigning authority (CNA) scores it 8.8, NVD 5.5.

Low priority for now. Upgrade to Linux Linux 6285516170f9e2f04b9dbf1e5100e0d7cbac22b4, 6bfe7ae9bbd9734751b853e2d2e1c13e8b46fd2d, 823435bd23108d6f8be89ea2d025c0e2e3769c51; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix node corruption in ar->arvifs list In current WLAN recovery code flow, ath12k_core_halt() only reinitializes the "arvifs" list head. This will cause the list node immediately following the list head to become an invalid list node. Because the prev of that node still points to the list head "arvifs", but the next of the list head "arvifs" no longer points to that list node. When a WLAN recovery occurs during the execution of a vif removal, and it happens before the spin_lock_bh(&ar->data_lock) in ath12k_mac_vdev_delete(), list_del() will detect the previously mentioned situation, thereby triggering a kernel panic. The fix is to remove and reinitialize all vif list nodes from the list head "arvifs" during WLAN halt. The reinitialization is to make the list nodes valid, ensuring that the list_del() in ath12k_mac_vdev_delete() can execute normally. Call trace: __list_del_entry_valid_or_report+0xd4/0x100 (P) ath12k_mac_remove_link_interface.isra.0+0xf8/0x2e4 [ath12k] ath12k_scan_vdev_clean_work+0x40/0x164 [ath12k] cfg80211_wiphy_work+0xfc/0x100 process_one_work+0x164/0x2d0 worker_thread+0x254/0x380 kthread+0xfc/0x100 ret_from_fork+0x10/0x20 The change is mostly copied from the ath11k patch: https://lore.kernel.org/all/20250320053145.3445187-1-quic_stonez@quicinc.com/ Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
