Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the Linux kernel within the rockchip RGA component. The rga get frame() function may return an ERR PTR(-EINVAL) when a buffer type is invalid or unsupported. Because the rga buf init() function fails to check this return value, it unconditionally dereferences the pointer when accessing f->size, leading to a potential pointer dereference issue.
Recommendations Implement proper ERR PTR checking in the rga buf init() function to ensure errors are returned and invalid pointers are not dereferenced.
