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