In the Linux kernel, the following vulnerability has been resolved:
media: rockchip: rga: Fix possible ERR_PTR dereference in rga_buf_init()
rga_get_frame() can return ERR_PTR(-EINVAL) when buffer type is unsupported or invalid. rga_buf_init() does not check the return value and unconditionally dereferences the pointer when accessing f->size.
Add proper ERR_PTR checking and return the error to prevent dereferencing an invalid pointer.
AnalysisAI
Local denial-of-service in Linux kernel's Rockchip RGA media driver allows authenticated users with low privileges to crash the system through NULL pointer dereference. The vulnerability affects kernel versions 6.8+ containing the Rockchip RGA driver, where rga_buf_init() fails to validate ERR_PTR returns from rga_get_frame() before dereferencing frame size. …
