CVE-2024-46739

In the Linux kernel, the following vulnerability has been resolved: uio_hv_generic: Fix kernel NULL pointer dereference in hv_uio_rescind For primary VM Bus channels, primary_channel pointer is always NULL. This pointer is valid only for the secondary channels. Also, rescind callback is meant for primary channels only. Fix NULL pointer dereference by retrieving the device_obj from the parent for the primary channel.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: uio_hv_generic: Corrija la desreferencia del puntero NULL del kernel en hv_uio_rescind. Para los canales de bus de VM principales, el puntero primary_channel siempre es NULL. Este puntero solo es válido para los canales secundarios. Además, la devolución de llamada rescind está destinada solo para los canales principales. Corrija la desreferencia del puntero NULL recuperando el device_obj del padre para el canal principal.
