CVE-2026-46103

In the Linux kernel, the following vulnerability has been resolved: can: ucan: fix devres lifetime USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers...

CVE-2026-46103

CVE-2026-46103 affects the Linux kernel, specifically the USB stack where can: ucan fixes the devres lifetime. The root cause is that resources bound to USB interfaces were not guaranteed to outlive the parent USB device, leading to memory leaks when drivers unbind (e.g., during probe deferrals o...

CVE-2026-23298

A flaw was found in the Linux kernel's CAN Controller Area Network ucan driver. This vulnerability allows a connected ucan device to send a message with a zero-length field. Such a message can trigger an infinite loop within the driver, causing the system to hang. This ultimately leads to a denia...
