Device-managed interrupt requests and resource groups in the altr_portb_setup() function were improperly associated with a temporary per-port device structure rather than the parent device. A local privileged user could trigger this flaw during device setup or teardown, leading to improper resource management. This issue could result in system instability or a Denial of Service (DoS).\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-10-19 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-98435.json)\n\n**kernel: EDAC/altera: Use parent device for devres in altr_portb_setup()** — rated Moderate by Red Hat.
