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.
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
