Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability has been resolved in the Linux kernel, specifically in the drm/edid component. The function
connector bad edid() assumed that the memory for the EDID passed to it was big enough to hold edid[0x7e] + 1 blocks of data, ignoring the fact that it was passed num blocks which indicated the allocated memory for the EDID. This issue is important for handling cases where there's an error in the first block of the EDID. A bounds check has been added to fix this issue.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
