CVE-2026-43369

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd: Fix NULL pointer dereference in device cleanup<br /> <br /> When GPU initialization fails due to an unsupported HW block<br /> IP blocks may have a NULL version pointer. During cleanup in<br /> amdgpu_device_fini_hw, the code calls amdgpu_device_set_pg_state and<br /> amdgpu_device_set_cg_state which iterate over all IP blocks and access<br /> adev-&gt;ip_blocks[i].version without NULL checks, leading to a kernel<br /> NULL pointer dereference.<br /> <br /> Add NULL checks for adev-&gt;ip_blocks[i].version in both<br /> amdgpu_device_set_cg_state and amdgpu_device_set_pg_state to prevent<br /> dereferencing NULL pointers during GPU teardown when initialization has<br /> failed.<br /> <br /> (cherry picked from commit b7ac77468cda92eecae560b05f62f997a12fe2f2)
