CVE-2024-50234

Wi-Fi failure via stale resume interrupt race

Published Nov 9, 2024 · Updated May 11, 2026

A race condition in affected Linux builds from 2.6.25 through 6.11.6 allows local users to interrupt iwl4965 Wi-Fi service after resume. The il_pci_resume function enables interrupts without first clearing a stale device interrupt, racing resume against restart work queued by the interrupt handler. Exposure requires iwl4965 hardware and hibernation; the race can leave the wireless hardware unavailable and trigger a kernel warning.
