Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: can: gsusb: gsusbreceivebulkcallback: fixed a URB memory leak. In gscanopen, the URBs for USB-in transfers are allocated, added to the parent-rxsubmitted anchor, and then submitted. In the complete callback...

CVE-2026-74505

A flaw was found in the ALSA 6fire driver within the Linux kernel. During error handling in the probe phase, the driver failed to properly manage a pending USB Request Block URB before freeing associated resources. This oversight could lead to a Use-After-Free UAF vulnerability. A local attacker...

PT-2026-69770

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the dummy hcd component of the USB gadget subsystem where a shared usb request dum-fifo req can be reused prematurely during the giveback process. The dummy queue...

CVE-2026-64585 can: esd_usb: kill anchored URBs before freeing netdevs

In the Linux kernel, the following vulnerability has been resolved: can: esdusb: kill anchored URBs before freeing netdevs esdusbdisconnect frees each CAN netdev with freecandev inside its per-netdev loop and only calls unlinkallurbsdev afterwards. The per-netdev private data struct esdusbnetpriv...

CVE-2026-64335

A flaw was found in the Linux kernel's USB serial digiacceleport driver. This vulnerability occurs when a port is closed while it is in a throttled state, preventing the read Urban Request Block URB from being resubmitted. As a result, the affected port will cease to receive any further data,...

CVE-2026-64491

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y: us144mkii: fix work UAF on disconnect tascamdisconnect cancels capturework and midiinwork before usbkillanchoredurbs kills the capture/MIDI-in URBs. Those URBs self-resubmit, and their completion handlers reschedule...

CVE-2026-64491

CVE-2026-64491 affects the Linux kernel’s ALSA subsystem for usx2y/us144mkii. The bug arises in tascam_disconnect(): capture_work and midi_in_work are canceled after URBs are killed, but some URBs may complete in the window between cancel_work_sync() and usb_kill_anchored_urbs(), re‑arming the wo...
