CVE-2024-38547

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. Por lo tanto, se activa una desreferencia de puntero nulo.

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.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
