CVE-2026-53107

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the libertas wifi driver where the system attempts to kill USB Request Blocks (URBs) within an interrupt context. Serialization for the transmission path was previously enforced using usb kill urb() or usb kill anchored urbs() to prevent new transmissions before previous URBs completed. However, because usb tx block() can be invoked from an interrupt context, such as the Host Controller Driver (HCD) giveback path, it may cause the system to sleep, which is prohibited in interrupt contexts.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
