CVE-2019-19054

Priority
Description
A memory leak in the cx23888_ir_probe() function in
drivers/media/pci/cx23885/cx23888-ir.c in the Linux kernel through 5.3.11
allows attackers to cause a denial of service (memory consumption) by
triggering kfifo_alloc() failures, aka CID-a7b2df76b42b.
Ubuntu-Description
It was discovered that the Conexant 23885 TV card device driver for the
Linux kernel did not properly deallocate memory in some error conditions. A
local attacker could use this to cause a denial of service (memory
exhaustion).
