CVE-2026-74677

CVE-2026-74677 is a use-after-free in the Linux kernel's ipheth USB network driver. The root cause is that ipheth_sndbulk_callback() re-arms the carrier_work delayed work on any non-zero URB status without checking whether the interface is still up. After ipheth_close() drains the work, a late UR...

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb: Fix UAF at delayed release of MIDI2 EPs The recent fix for UAF in umptoendpoint caused another UAF because it tries to dereference the UMP endpoint object, but this might be executed at a delayed context where the...

CVE-2026-74642

CVE-2026-74642 is a Use-After-Free (UAF) vulnerability in the Linux kernel's ALSA USB subsystem , specifically in the handling of MIDI 2.0 (UMP) endpoints . A prior fix for a UAF in ump_to_endpoint() inadvertently introduced a second UAF: the code dereferences the UMP endpoint object in a delayed...

CVE-2026-74639

CVE-2026-74639 is a use-after-free in the Linux kernel's ALSA us144mkii driver (Tascam US-144MKII USB audio interface). The root cause is that capture_urb_complete() resubmits capture URBs without re-anchoring them. Since anchoring is a property of a submission (not the URB itself), the anchor be...
