CVE-2019-19057

Published: 18 November 2019

Two memory leaks in the mwifiex_pcie_init_evt_ring() 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 mwifiex_map_pci_memory() failures, aka CID-d10dcb615c8e.

From the Ubuntu Security Team

It was discovered that multiple memory leaks existed in the Marvell WiFi-Ex Driver for the Linux kernel. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion).
