https://notcve.org/view.php?id=CVE-2024-42121
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check index msg_id before read or write [WHAT] msg_id is used as an array index and it cannot be a negative value, and therefore cannot be equal to MOD_HDCP_MESSAGE_ID_INVALID (-1). [HOW] Check whether msg_id is valid before reading and setting. This fixes 4 OVERRUN issues reported by Coverity. • https://git.kernel.org/stable/c/b5b8837d066cc182ff69fb5629ad32ade5484567 https://git.kernel.org/stable/c/fbb0701af9734cff13917a4b98b5ee9da2fde48d https://git.kernel.org/stable/c/ae91ffbc8b8d942e3e7f188728cad557b7ed5ee4 https://git.kernel.org/stable/c/9933eca6ada0cd612e19522e7a319bcef464c0eb https://git.kernel.org/stable/c/a31ea49dc8064a557565725cf045944307476a6e https://git.kernel.org/stable/c/59d99deb330af206a4541db0c4da8f73880fba03 •

https://notcve.org/view.php?id=CVE-2024-42120
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check pipe offset before setting vblank pipe_ctx has a size of MAX_PIPES so checking its index before accessing the array. This fixes an OVERRUN issue reported by Coverity. • https://git.kernel.org/stable/c/b2e9abc95583ac7bbb2c47da4d476a798146dfd6 https://git.kernel.org/stable/c/0b3702f9d43d163fd05e43b7d7e22e766dbef329 https://git.kernel.org/stable/c/d2c3645a4a5ae5d933b4116c305d9d82b8199dbf https://git.kernel.org/stable/c/96bf81cc1bd058bb8af6e755a548e926e934dfd1 https://git.kernel.org/stable/c/c5ec2afeeee4c91cebc4eff6d4f1ecf4047259f4 https://git.kernel.org/stable/c/5396a70e8cf462ec5ccf2dc8de103c79de9489e6 •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Skip finding free audio for unknown engine_id [WHY] ENGINE_ID_UNKNOWN = -1 and can not be used as an array index. Plus, it also means it is uninitialized and does not need free audio. [HOW] Skip and return NULL.

https://notcve.org/view.php?id=CVE-2024-42118
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Do not return negative stream id for array [WHY] resource_stream_to_stream_idx returns an array index and it return -1 when not found; however, -1 is not a valid array index number. [HOW] When this happens, call ASSERT(), and return a zero instead.
