Description
A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-db8fd2cde932.
A flaw was found in the way the mwifiex PCIE driver in the Linux kernel handled resource cleanup on a DMA mapping error. This flaw allows an attacker able to trigger the DMA mapping error to crash the system.
