CWE-401Published: November 18, 2019· Updated: Jun 17, 2026
3.3
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2019-19057 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
