CVE-2025-21956

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Assign normalized_pix_clk when color depth = 14 [WHY & HOW] A warning message "WARNING: CPU: 4 PID: 459 at ... /dc_resource.c:3397 calculate_phy_pix_clks+0xef/0x100 [amdgpu]" occurs because the display_color_depth == COLOR_DEPTH_141414 is not handled. This is observed in Radeon RX 6600 XT. It is fixed by assigning pix_clk * (14 * 3) / 24 - same as the rests. Also fixes the indentation in get_norm_pix_clk. (cherry picked from commit 274a87eb389f58eddcbc5659ab0b180b37e92775)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Asignar normalized_pix_clk cuando la profundidad de color es 14 [POR QUÉ Y CÓMO] Se produce un mensaje de advertencia "ADVERTENCIA: CPU: 4 PID: 459 en ... /dc_resource.c:3397 calculate_phy_pix_clks+0xef/0x100 [amdgpu]" porque no se gestiona la profundidad de color de la pantalla = COLOR_DEPTH_141414. Esto se observa en la Radeon RX 6600 XT. Se soluciona asignando pix_clk * (14 * 3) / 24, igual que el resto. También se corrige la sangría en get_norm_pix_clk.
