A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering alloc_page() failures, aka CID-b4b814fec1a5.
A flaw was found in the Linux kernel. The Intel Wireless WiFi MVM Firmware driver mishandles resource cleanup during device coredump. An attacker able to trigger the device coredump and system-wide out of memory conditions at the same time could use this flaw to crash the system. The highest threat from this vulnerability is to system availability.
