Descriptions
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix NULL pointer dereference in i40e_dbg_dump_desc
When trying to dump VFs VSI RX/TX descriptors
using debugfs there was a crash
due to NULL pointer dereference in i40e_dbg_dump_desc.
Added a check to i40e_dbg_dump_desc that checks if
VSI type is correct for dumping RX/TX descriptors.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: i40e: Se corrigió la desreferencia del puntero NULL en i40e_dbg_dump_desc Al intentar volcar los descriptores VF VSI RX/TX usando debugfs, se produjo un bloqueo debido a la desreferencia del puntero NULL en i40e_dbg_dump_desc. Se agregó una verificación a i40e_dbg_dump_desc que verifica si el tipo de VSI es correcto para volcar descriptores RX/TX.
