1) Memory leak (CVE-ID: CVE-2019-19059)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the "iwl_pcie_ctxt_info_gen3_init()" function in "drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c" file. A remote attacker on the local network can cause a denial of service condition (memory consumption) by triggering "iwl_pcie_init_fw_sec() or dma_alloc_coherent()" failures.
