CVE-2019-19057: Low severity Linux Linux kernel vulnerability

Published Nov 18, 2019
·
Updated

Two memory leak flaws were found in the Linux kernel's mwifiexpcieinitevtring() function. A local attacker, able to reload the kernel module or hotplug Marvell WiFi hardware using this driver, can cause a denial of service (memory consumption) by triggering mwifiexmappcimemory() failures.

Other sources

Two memory leaks in the mwifiexpcieinitevtring() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering mwifiexmappcimemory() failures, aka CID-d10dcb615c8e.
