  3. 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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net:hns3: se corrige un problema de bloqueo cuando se configura TC durante el reinicio Cuando se configura TC durante el proceso de reinicio, puede causar un bloqueo, el flujo es el siguiente: 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() En el proceso de reinicio, el controlador DESACTIVARÁ el puerto y luego UINIT; en este caso, el proceso de configuración tc DESACTIVARÁ el puerto antes de UINIT, lo que provocará el problema. Agrega un proceso DESACTIVADO en UINIT para solucionarlo.
