Vulnerability from github – Published: 2024-10-21 18:30 – Updated: 2024-11-01 21:31

Details

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

drm/amd/display: Increase array size of dummy_boolean

[WHY] dml2_core_shared_mode_support and dml_core_mode_support access the third element of dummy_boolean, i.e. hw_debug5 = &s->dummy_boolean[2], when dummy_boolean has size of 2. Any assignment to hw_debug5 causes an OVERRUN.

[HOW] Increase dummy_boolean's array size to 3.

This fixes 2 OVERRUN issues reported by Coverity.

Severity

5.5 (Medium)
