In the Linux kernel, the following vulnerability has been resolved: net: mscc: ocelot: add missing lock protection in ocelotportxmitinj ocelotportxmitinj calls ocelotcaninject and ocelotportinjectframe without holding the injection group lock. Both functions contain lockdepassertheld for the...

CVE-2026-46103

In the Linux kernel, a fix for devres lifetime in the can: ucan path addresses memory-management where USB driver resources tied to an interface were not properly released when the driver is unbound (e.g., probe deferral or config changes). The issue affects USB drivers binding to interfaces and ...

EUVD-2026-32486

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...
