CVE-2026-46263

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An out-of-bounds access issue exists in the AMD display driver within the Linux kernel. The eng id variable is used as an index for the stream enc regs[] array, which contains only five entries. If eng id is negative or equal to 5 (ENGINE ID DIGF), the system may access memory beyond the array boundaries. This occurs within the dcn35 stream encoder create() function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
