# CVE-2025-39996: media: b2c2: Fix use-after-free causing by irq_check_work in flexcop_pci_remove CVE-2025-39996 is fixed in 44 products on 1 platform, first by DEBIAN-CVE-2025-39996, released October 15, 2025. It is not reported as exploited. Patch Radar priority: Urgent. - Web page: https://patchblox.com/security/cve/CVE-2025-39996 - Priority: Urgent - CVSS: 9.8 (Critical) - EPSS: 0.0023 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Oct 15, 2025 - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-39996 ## Description In the Linux kernel, the following vulnerability has been resolved: media: b2c2: Fix use-after-free causing by irq_check_work in flexcop_pci_remove The original code uses cancel_delayed_work() in flexcop_pci_remove(), which does not guarantee that the delayed work item irq_check_work has fully completed if it was already running. This leads to use-after-free scenarios where flexcop_pci_remove() may free the flexcop_device while irq_check_work is still active and attempts to dereference the device. A typical race condition is illustrated below: CPU 0 (remove) | CPU 1 (delayed work callback) flexcop_pci_remove() | flexcop_pci_irq_check_work() cancel_delayed_work() | flexcop_device_kfree(fc_pci->fc_dev) | | fc = fc_pci->fc_dev; // UAF This is confirmed by a KASAN report: ================================================================== BUG: KASAN: slab-use-after-free in __run_timer_base.part.0+0x7d7/0x8c0 Write of size 8 at addr ffff8880093aa8c8 by task bash/135 ...

Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure that the delayed work item is properly canceled and any executing delayed work has finished before the device memory is deallocated. This bug was initially identified through static analysis. To reproduce and test it, I simulated the B2C2 FlexCop PCI device in QEMU and introduced artificial delays within the flexcop_pci_irq_check_work() function to increase the likelihood of triggering the bug. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | bpftool ol 8 | 0:5.15.0-315.196.5.1.el9uek |
