Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An out-of-bounds read occurs in the drm log draw kmsg record() function when processing a message with a length of 0. Because the len variable is an unsigned integer, subtracting 1 from it when it is 0 causes the value to wrap to UINT MAX, leading to an invalid memory access while attempting to strip a trailing newline.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
