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.

(cherry picked from commit dbb02b4755f8c1f3773263f2d779872c1c0c073a)
