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...

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-2026-64334 USB: serial: digi_acceleport: fix hard lockup on disconnect

In the Linux kernel, the following vulnerability has been resolved: USB: serial: digiacceleport: fix hard lockup on disconnect If submitting the OOB write urb fails persistently e.g if the device is being disconnected the driver would loop indefinitely with interrupts disabled. Check for urb...

CVE-2026-64335

CVE-2026-64335 affects the digi_acceleport USB serial driver in the Linux kernel. If a serial port is closed while throttled, the read URB is never resubmitted, leaving the port unable to receive any further data until the device is reconnected or the driver is rebound. The fix clears throttle fl...

PT-2026-64556

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the digi acceleport USB serial driver where the read USB Request Block URB—a data structure used to manage USB transfers—is not resubmitted if the port is closed while...

CVE-2026-63874

A flaw was found in the Linux kernel's USB Management Component Transport Protocol MCTP driver. A race condition exists between the completion of a USB Request Block URB and the cancellation of retry operations during the driver's shutdown process. This timing issue can cause a URB to be re-queue...
