Doc Text:
A flaw was found in the Linux kernel's `rockchip: rga` driver. An attacker providing an unsupported or invalid buffer type to the `rga_buf_init()` function could cause a dereference of an invalid pointer. This could lead to a system crash, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-05-08 14:03:41 UTC 
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.
