In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/vcn4: avoid rereading IB param length
Reuse the parameter length returned by
vcn_v4_0_enc_find_ib_param() instead of rereading it from
the IB.
This avoids a potential TOCTOU issue if the IB contents
change between reads.
