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: drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is assigned to mhdp_state->current_mode, and there is a dereference of it in drm_mode_set_name(), which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Fix this bug add a check of mhdp_state->current_mode. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm: bridge: cdns-mhdp8546: corrige posible desreferencia del puntero nulo En cdns_mhdp_atomic_enable(), el valor de retorno de drm_mode_duplicate() se asigna a mhdp_state->current_mode, y hay una desreferencia de él en drm_mode_set_name(), lo que conducirá a una desreferencia del puntero NULL en caso de falla de drm_mode_duplicate().

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.

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.
