It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-49543 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-49543/ (Markdown: https://insights.sbomify.com/CVE-2022-49543/index.md)","id":"CVE-2022-49543","markdown":"https://insights.sbomify.com/CVE-2022-49543/index.md","name":"CVE-2022-49543","record":{"aliases":["DEBIAN-CVE-2022-49543","GHSA-p6c8-wm8r-hj4h","ROOT-OS-DEBIAN-11-CVE-2022-49543","ROOT-OS-UBUNTU-2204-CVE-2022-49543","UBUNTU-CVE-2022-49543"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A bug in the ath11k Wi-Fi driver causes a kernel warning during firmware crash simulation, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nath11k: fix the warning of dev_wake in mhi_pm_disable_transition()\n\nWhen test device recovery with below command, it has warning in message\nas below.\necho assert \u003e /sys/kernel/debug/ath11k/wcn6855\\ hw2.0/simulate_fw_crash\necho assert \u003e /sys/kernel/debug/ath11k/qca6390\\ hw2.0/simulate_fw_crash\n\nwarning message:\n[ 1965.642121] ath11k_pci 0000:06:00.0: simulating firmware assert crash\n[ 1968.471364] ieee80211 phy0: Hardware restart was requested\n[ 1968.511305] ------------[ cut here ]------------\n[ 1968.511368] WARNING: CPU: 3 PID: 1546 at drivers/bus/mhi/core/pm.c:505 mhi_pm_disable_transition+0xb37/0xda0 [mhi]\n[ 1968.511443] Modules linked in: ath11k_pci ath11k mac80211 libarc4 cfg80211 qmi_helpers qrtr_mhi mhi qrtr nvme nvme_core\n[ 1968.511563] CPU: 3 PID: 1546 Comm: kworker/u17:0 Kdump: loaded Tainted: G        W         5.17.0-rc3-wt-ath+ #579\n[ 1968.511629] Hardware name: Intel(R) Client Systems NUC8i7HVK/NUC8i7HVB, BIOS HNKBLi70.86A.0067.2021.0528.1339 05/28/2021\n[ 1968.511704] Workqueue: mhi_hiprio_wq mhi_pm_st_worker [mhi]\n[ 1968.511787] RIP: 0010:mhi_pm_disable_transition+0xb37/0xda0 [mhi]\n[ 1968.511870] Code: a9 fe ff ff 4c 89 ff 44 89 04 24 e8 03 46 f6 e5 44 8b 04 24 41 83 f8 01 0f 84 21 fe ff ff e9 4c fd ff ff 0f 0b e9 af f8 ff ff \u003c0f\u003e 0b e9 5c f8 ff ff 48 89 df e8 da 9e ee e3 e9 12 fd ff ff 4c 89\n[ 1968.511923] RSP: 0018:ffffc900024efbf0 EFLAGS: 00010286\n[ 1968.511969] RAX: 00000000ffffffff RBX: ffff88811d241250 RCX: ffffffffc0176922\n[ 1968.512014] RDX: 0000000000000000 RSI: 0000000000000004 RDI: ffff888118a90a24\n[ 1968.512059] RBP: ffff888118a90800 R08: 0000000000000000 R09: ffff888118a90a27\n[ 1968.512102] R10: ffffed1023152144 R11: 0000000000000001 R12: ffff888118a908ac\n[ 1968.512229] R13: ffff888118a90928 R14: dffffc0000000000 R15: ffff888118a90a24\n[ 1968.512310] FS:  0000000000000000(0000) GS:ffff888234200000(0000) knlGS:0000000000000000\n[ 1968.512405] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 1968.512493] CR2: 00007f5538f443a8 CR3: 000000016dc28001 CR4: 00000000003706e0\n[ 1968.512587] Call Trace:\n[ 1968.512672]  \u003cTASK\u003e\n[ 1968.512751]  ? _raw_spin_unlock_irq+0x1f/0x40\n[ 1968.512859]  mhi_pm_st_worker+0x3ac/0x790 [mhi]\n[ 1968.512959]  ? mhi_pm_mission_mode_transition.isra.0+0x7d0/0x7d0 [mhi]\n[ 1968.513063]  process_one_work+0x86a/0x1400\n[ 1968.513184]  ? pwq_dec_nr_in_flight+0x230/0x230\n[ 1968.513312]  ? move_linked_works+0x125/0x290\n[ 1968.513416]  worker_thread+0x6db/0xf60\n[ 1968.513536]  ? process_one_work+0x1400/0x1400\n[ 1968.513627]  kthread+0x241/0x2d0\n[ 1968.513733]  ? kthread_complete_and_exit+0x20/0x20\n[ 1968.513821]  ret_from_fork+0x22/0x30\n[ 1968.513924]  \u003c/TASK\u003e\n\nReason is mhi_deassert_dev_wake() from mhi_device_put() is called\nbut mhi_assert_dev_wake() from __mhi_device_get_sync() is not called\nin progress of recovery.
