Oracle Linux: CVE-2019-12382: ELSA-2019-4746: Unbreakable Enterprise kernel security update (IMPORTANT) (Multiple Advisories)

An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL pointer dereference
A flaw was found in the Linux kernel’s implementation of Extended Display Identification Data (EDID) technology. A firmware identifier string is duplicated with the kstrdup function, and the allocation may fail under very low memory conditions. An attacker could abuse this flaw by causing a Denial of Service and crashing the system.
