CVE-2026-45849

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: mscc: ocelot: add missing lock protection in ocelot_port_xmit_inj()<br /> <br /> ocelot_port_xmit_inj() calls ocelot_can_inject() and<br /> ocelot_port_inject_frame() without holding the injection group lock.<br /> Both functions contain lockdep_assert_held() for the injection lock,<br /> and the correct caller felix_port_deferred_xmit() properly acquires<br /> the lock using ocelot_lock_inj_grp() before calling these functions.<br /> <br /> Add ocelot_lock_inj_grp()/ocelot_unlock_inj_grp() around the register<br /> injection path to fix the missing lock protection. The FDMA path is not<br /> affected as it uses its own locking mechanism.
