CVE-2024-38547 in Linux
Riassunto
di MITRE • 19/06/2024
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.
