A flaw was found in the Linux kernel's Altera EDAC (Error Detection and Correction) driver. 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).
kernel: EDAC/altera: Use parent device for devres in altr_portb_setup() — rated Moderate by Red Hat. Released 2026-10-18, updated 2026-10-19.
