{"id":"CVE-2026-68107","summary":"drm/amdgpu/vcn4: avoid rereading IB param length","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu/vcn4: avoid rereading IB param length\n\nReuse the parameter length returned by\nvcn_v4_0_enc_find_ib_param() instead of rereading it from\nthe IB.\n\nThis avoids a potential TOCTOU issue if the IB contents\nchange between reads.\n\n(cherry picked from commit
