Vulnerability from github – Published: 2024-10-09 15:32 – Updated: 2026-10-30 15:31

Details

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

drm/amd/display: Avoid overflow from uint32_t to uint8_t

[WHAT & HOW] dmub_rb_cmd's ramping_boundary has size of uint8_t and it is assigned 0xFFFF. Fix it by changing it to uint8_t with value of 0xFF.

This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

Severity

5.5 (Medium)
