Descriptions

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.

Una pérdida de memoria en la función mwifiex_pcie_alloc_cmdrsp_buf() en el archivo drivers/net/wireless/marvell/mwifiex/pcie.c en el kernel de Linux versiones hasta la versión 5.3.11, permite a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función mwifiex_map_pci_memory(), también se conoce como 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.
