Description

Multiple memory leaks in the iwl_pcie_ctxt_info_gen3_init() function in drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering iwl_pcie_init_fw_sec() or dma_alloc_coherent() failures, aka CID-0f4f199443fa. A flaw was found in the way the Intel Wireless driver in the Linux kernel handled resource cleanup during Gen 3 device initialization. This flaw allows an attacker with the ability to restrict access to DMA coherent memory on device initialization, to crash the system.
