The vulnerability exists due to memory leak within the "mwifiex_pcie_alloc_cmdrsp_buf()" function in "drivers/net/wireless/marvell/mwifiex/pcie.c" file. A remote attacker on the local network can cause a denial of service condition (memory consumption) by triggering "mwifiex_map_pci_memory()" failures.

Mitigation

Install update from vendor's website.
