https://notcve.org/view.php?id=CVE-2024-44995
In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix a deadlock problem when config TC during resetting When config TC during the reset process, may cause a deadlock, the flow is as below: pf reset start │ ▼ ...... setup tc │ │ ▼ ▼ DOWN: napi_disable() napi_disable()(skip) │ │ │ ▼ ▼ ...... ...... │ │ ▼ │ napi_enable() │ ▼ UINIT: netif_napi_del() │ ▼ ...... │ ▼ INIT: netif_napi_add() │ ▼ ...... global reset start │ │ ▼ ▼ UP: napi_enable()(skip) ...... │ │ ▼ ▼ ...... napi_disable() In reset process, the driver will DOWN the port and then UINIT, in this case, the setup tc process will UP the port before UINIT, so cause the problem. Adds a DOWN process in UINIT to fix it. • https://git.kernel.org/stable/c/bb6b94a896d4dd4dcdeccca87c3fd22521c652c0 https://git.kernel.org/stable/c/67492d4d105c0a6321b00c393eec96b9a7a97a16 https://git.kernel.org/stable/c/fc250eca15bde34c4c8f806b9d88f55bd56a992c https://git.kernel.org/stable/c/195918217448a6bb7f929d6a2ffffce9f1ece1cc https://git.kernel.org/stable/c/6ae2b7d63cd056f363045eb65409143e16f23ae8 https://git.kernel.org/stable/c/fa1d4de7265c370e673583ac8d1bd17d21826cd9 https://git.kernel.org/stable/c/de37408d5c26fc4a296a28a0c96dcb814219bfa1 https://git.kernel.org/stable/c/be5e816d00a506719e9dbb1a9c861c5ce •
