CVE-2019-19053
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
