{"id":"CVE-2025-21956","summary":"drm/amd/display: Assign normalized_pix_clk when color depth = 14","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Assign normalized_pix_clk when color depth = 14\n\n[WHY & HOW]\nA warning message \"WARNING: CPU: 4 PID: 459 at ... /dc_resource.c:3397\ncalculate_phy_pix_clks+0xef/0x100 [amdgpu]\" occurs because the\ndisplay_color_depth == COLOR_DEPTH_141414 is not handled. This is\nobserved in Radeon RX 6600 XT.\n\nIt is fixed by assigning pix_clk * (14 * 3) / 24 - same as the rests.\n\nAlso fixes the indentation in get_norm_pix_clk.\n\n(cherry picked from commit 274a87eb389f58eddcbc5659ab0b180b37e92775)","modified":"2026-04-16T04:31:24.542823082Z","published":"2025-04-01T15:46:56.219Z","related":["SUSE-SU-2025:01600-1","SUSE-SU-2025:01614-1","SUSE-SU-2025:01707-1","SUSE-SU-2025:01919-1","SUSE-SU-2025:01951-1","SUSE-SU-2025:01964-1","SUSE-SU-2025:01967-1","SUSE-SU-2025:20192-1","SUSE-SU-2025:20206-1","SUSE-SU-2025:20270-1","SUSE-SU-2025:20283-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/21xxx/CVE-2025-21956.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0174a2e5770efee9dbd4b58963ed4d939298ff5e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/04f90b505ad3a6eed474bbaa03167095fef5203a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0c0016712e5dc23ce4a7e673cbebc24a535d8c8a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/27df30106690969f7d63604f0d49ed8e9bffa2cb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79e31396fdd7037c503e6add15af7cb00633ea92"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a8f77e1658d78e4a8bb227a83bcee67de97f7634"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cca3ab74f90176099b6392e8e894b52b27b3d080"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc831b38680c47d07e425871a9852109183895cf"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/21xxx/CVE-2025-21956.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-21956"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c"},{"fixed":"cca3ab74f90176099b6392e8e894b52b27b3d080"},{"fixed":"0174a2e5770efee9dbd4b58963ed4d939298ff5e"},{"fixed":"0c0016712e5dc23ce4a7e673cbebc24a535d8c8a"},{"fixed":"dc831b38680c47d07e425871a9852109183895cf"},{"fixed":"a8f77e1658d78e4a8bb227a83bcee67de97f7634"},{"fixed":"04f90b505ad3a6eed474bbaa03167095fef5203a"},{"fixed":"27df30106690969f7d63604f0d49ed8e9bffa2cb"},{"fixed":"79e31396fdd7037c503e6add15af7cb00633ea92"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-21956.json"}}],"schema_version":"1.7.5"}
