CVE-2019-19059 is a medium-severity vulnerability rated 4.7/10 on the CVSS scale. 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.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
