Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Avoid overflow assignment in link_dp_cts

sampling_rate is an uint8_t but is assigned an unsigned int, and thus it can overflow. As a result, sampling_rate is changed to uint32_t.

Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should only be assigned to a value less or equal than 4.

This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

Severity
5.5 (Medium)
