Description
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.
Ubuntu-Description
It was discovered that the Intel(R) Wi-Fi device driver in the Linux kernel
