CVE-2019-12382

Published: 28 May 2019

** DISPUTED ** 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.

Priority

Negligible

CVSS 3 base score: 5.5

Notes

AuthorNote

There's no security impact here as there's no chance of a NULL
pointer derefence. I've requested that MITRE reject this CVE.
I've reviewed our Disco, Cosmic, Bionic, and Xenial kernels. There's
no security impact here so we'll ignore this issue.
