CVSS v3.1
5.5
Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 5.1.5
Description
An issue was discovered in the
drm load edid firmware function in the Linux kernel, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash) due to an unchecked kstrdup of fwstr. The vendor disputes this issue as not being a vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL pointer dereference.Recommendations
For Linux kernel versions through 5.1.5, as a temporary workaround, consider disabling the
drm load edid firmware function until a patch is available.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.DoS
