CVE-2026-68107

High

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)
