CVE-2026-23324

MediumCVSS 5.5
Published: Updated: Translated: NVD NIST

Summary

In the Linux kernel, the can: usb: etas_es58x driver did not anchor the urb in the read bulk callback before submitting it. If usb_kill_anchored_urbs() was called, this could leak the urb.

Risk Assessment

Leaking urb structures can exhaust kernel resources and destabilize the system under heavy use of the CAN USB interface.

Recommendation

Update the Linux kernel to a version containing the fix for the etas_es58x driver.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: can: usb: etas_es58x: correctly anchor the urb in the read bulk callback When submitting an urb, that is using the anchor pattern, it needs to be anchored before submitting it otherwise it could be leaked if usb_kill_anchored_urbs() is called. This logic is correctly done elsewhere in the driver, except in the read bulk callback so do that here also.
