Description

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Initialize get_bytes_per_element's default to 1 Variables, used as denominators and maybe not assigned to other values, should not be 0. bytes_per_element_y & bytes_per_element_c are initialized by get_bytes_per_element() which should never return 0. This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.

Distribution advisory

This page covers CVE-2024-49892 as tracked by Ubuntu, for the package linux. The fix is available in version 6.8.0-54.56; earlier versions remain affected.
