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.

Fix

NULL Pointer Dereference

CWE-476
