CVE-2019-19053

Priority
Description
A memory leak in the rpmsg_eptdev_write_iter() function in
drivers/rpmsg/rpmsg_char.c in the Linux kernel through 5.3.11 allows
attackers to cause a denial of service (memory consumption) by triggering
copy_from_iter_full() failures, aka CID-bbe692e349e2.
Ubuntu-Description
It was discovered that the RPMSG character device interface in the Linux
kernel did not properly deallocate memory in certain error conditions. A
local attacker could possibly use this to cause a denial of service (kernel
memory exhaustion).
