CVE-2025-39996

CVE-2025-39996 affects the Linux kernel media driver for B2C2 FlexCop PCI. The underlying issue is a use-after-free caused by cancel_delayed_work() in flexcop_pci_remove(), which may free flexcop_device while irq_check_work is still running. The mitigation is to replace cancel_delayed_work() with...
