Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amdgpu/vcn4: avoid rereading IB param length<br /> <br /> Reuse the parameter length returned by<br /> vcn_v4_0_enc_find_ib_param() instead of rereading it from<br /> the IB.<br /> <br /> This avoids a potential TOCTOU issue if the IB contents<br /> change between reads.<br /> <br /> (cherry picked from commit dbb02b4755f8c1f3773263f2d779872c1c0c073a)
