Description

drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. A NULL pointer dereference flaw may occur in the Linux kernel’s drivers/net/wireless/marvell/libertas/if_sdio.c function, if the alloc_workqueue function return is not validated in time of failure. This flaw could allow an attacker to crash the system or leak kernel internal information.
