CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-38552 – drm/amd/display: Fix potential index out of bounds in color transformation function
https://notcve.org/view.php?id=CVE-2024-38552
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix potential index out of bounds in color transformation function Fixes index out of bounds issue in the color transformation function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, an error message is logged and the function returns false to indicate an error. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:405 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:406 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:407 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: corrige un posible índice fuera de los límites en la función de transformación de color. • https://git.kernel.org/stable/c/b629596072e5fa901c84f9e88d845a696ee32942 https://git.kernel.org/stable/c/604c506ca43fce52bb882cff9c1fdf2ec3b4029c https://git.kernel.org/stable/c/e280ab978c81443103d7c61bdd1d8d708cf6ed6d https://git.kernel.org/stable/c/04bc4d1090c343025d69149ca669a27c5b9c34a7 https://git.kernel.org/stable/c/ced9c4e2289a786b8fa684d8893b7045ea53ef7e https://git.kernel.org/stable/c/98b8a6bfd30d07a19cfacdf82b50f84bf3360869 https://git.kernel.org/stable/c/4e8c8b37ee84b3b19c448d2b8e4c916d2f5b9c86 https://git.kernel.org/stable/c/123edbae64f4d21984359b99c6e79fcde •

https://notcve.org/view.php?id=CVE-2024-38549
In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Add 0 size check to mtk_drm_gem_obj Add a check to mtk_drm_gem_init if we attempt to allocate a GEM object of 0 bytes. Currently, no such check exists and the kernel will panic if a userspace application attempts to allocate a 0x0 GBM buffer. Tested by attempting to allocate a 0x0 GBM buffer on an MT8188 and verifying that we now return EINVAL. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: drm/mediatek: Agregar verificación de tamaño 0 a mtk_drm_gem_obj Agregar una verificación a mtk_drm_gem_init si intentamos asignar un objeto GEM de 0 bytes. Actualmente, no existe tal verificación y el kernel entrará en pánico si una aplicación de espacio de usuario intenta asignar un búfer GBM 0x0. Probado intentando asignar un búfer GBM 0x0 en un MT8188 y verificando que ahora devolvemos EINVAL. • https://git.kernel.org/stable/c/119f5173628aa7a0c3cf9db83460d40709e8241d https://git.kernel.org/stable/c/79078880795478d551a05acc41f957700030d364 https://git.kernel.org/stable/c/be34a1b351ea7faeb15dde8c44fe89de3980ae67 https://git.kernel.org/stable/c/d17b75ee9c2e44d3a3682c4ea5ab713ea6073350 https://git.kernel.org/stable/c/0e3b6f9123726858cac299e1654e3d20424cabe4 https://git.kernel.org/stable/c/13562c2d48c9ee330de1077d00146742be368f05 https://git.kernel.org/stable/c/af26ea99019caee1500bf7e60c861136c0bf8594 https://git.kernel.org/stable/c/9489951e3ae505534c4013db4e76b1b5a •

In the Linux kernel, the following vulnerability has been resolved: media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries The allocation failure of mycs->yuv_scaler_binary in load_video_binaries() is followed with a dereference of mycs->yuv_scaler_binary after the following call chain: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() In unload_video_binaries(), it calls to ia_css_binary_unload with argument &pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer dereference is triggered. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: media: atomisp: ssh_css: corrige una desreferencia de puntero nulo en load_video_binaries La falla de asignación de mycs->yuv_scaler_binary en load_video_binaries() va seguida de una desreferencia de mycs->yuv_scaler_binary después de siguiente cadena de llamadas: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() En unload_video_binaries(), llama a ia_css_binary_unload con el argumento &pipe->pipe_settings.video.yuv_scaler_binary[i], que se refiere a la misma ranura de memoria que mycs->yuv_scaler_binary.

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix UAF for cq async event The refcount of CQ is not protected by locks. When CQ asynchronous events and CQ destruction are concurrent, CQ may have been released, which will cause UAF. Use the xa_lock() to protect the CQ refcount.
