When registering hardware discovery entries within the sysfs (system filesystem) interface, the driver fails to release allocated memory if a kernel object fails to register. An unexpected registration failure can cause the memory to remain uncollected, leading to a memory leak and a potential Denial of Service (DoS) due to resource exhaustion.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, … · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-98780.json)\n\n**kernel: drm/amdgpu: fix IP instance memory leak on kobject add failure** — rated Low by Red Hat.
