CVE-2025-38148
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: net: phy: mscc: Fix memory leak when using one step timestamping Fix memory leak when running one-step timestamping. When running one-step sync timestamping, the HW is configured to insert the TX time into the frame, so there is no reason to keep the skb anymore. As in this case the HW will never generate an interrupt to say that the frame was timestamped, then the frame will never released. Fix this by freeing the frame in case of one-step timestamping.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: phy: mscc: Se corrige la pérdida de memoria al usar el sellado de tiempo de un paso. Al ejecutar el sellado de tiempo de sincronización de un paso, el hardware está configurado para insertar la hora de transmisión en la trama, por lo que ya no hay razón para mantener el skb. Como en este caso, el hardware nunca generará una interrupción para indicar que la trama fue sellada, esta nunca se liberará. Se corrige liberando la trama en caso de sellado de tiempo de un paso."
