CVE-2026-68413

Kernel memory exhaustion via initialization leak

Published Aug 10, 2026 · Updated Aug 10, 2026

Resource leak in the Linux ipw2100 Wi-Fi driver allows local users to exhaust kernel memory during failed PCI initialization. The ipw2100_pci_init_one() error paths return after ipw2100_alloc_device() without releasing its allocation; pci_enable_device() failure requires separate cleanup before priv exists. Triggering the leak requires an affected kernel and Intel PRO/Wireless 2100 PCI hardware to encounter one of those initialization failures, and repeated triggers consume memory until service interruption.
