media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries

2024-05-30T07:49:39Z

[ Upstream commit 3b621e9e9e148c0928ab109ac3d4b81487469acb ] 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.

staging: vc04_services: fix information leak in create_component()

2024-04-03T13:32:45Z

commit f37e76abd614b68987abc8e5c22d986013349771 upstream. The m.u.component_create.pid field is for debugging and in the mainline kernel it's not used anything. However, it still needs to be set to something to prevent disclosing uninitialized stack data. Set it to zero. Fixes: 7b3ad5abf027 ("staging: Import the BCM2835 MMAL-based V4L2 camera driver.")

[ Upstream commit 34164202a5827f60a203ca9acaf2d9f7d432aac8 ] The get_channel_from_mode() function is supposed to return the channel which matches the mode. But it has a bug where if it doesn't find a matching channel then it returns the last channel. It should return NULL instead. Also remove an unnecessary NULL check on "channel".

[ Upstream commit 3a11887f7f11a6bb1f05e7f67b3ea20dadfec443 ] bit_size field holds size of slice, not slice + header. Because of HW quirks, driver can't program in just slice, but also preceding header. But that means that currently used bit_size is wrong (too small). Instead, just use size of whole buffer. There is no harm in doing this.
