Descriptions

In the Linux kernel, the following vulnerability has been resolved:

e1000e: change usleep_range to udelay in PHY mdic access

This is a partial revert of commit 6dbdd4de0362 ("e1000e: Workaround
for sporadic MDI error on Meteor Lake systems"). The referenced commit
used usleep_range inside the PHY access routines, which are sometimes
called from an atomic context. This can lead to a kernel panic in some
scenarios, such as cable disconnection and reconnection on vPro systems.

Solve this by changing the usleep_range calls back to udelay.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: e1000e: cambie usleep_range a udelay en el acceso mdic de PHY. Esta es una reversión parcial de el commit 6dbdd4de0362 ("e1000e: solución alternativa para errores MDI esporádicos en sistemas Meteor Lake"). El commit a la que se hace referencia usó usleep_range dentro de las rutinas de acceso PHY, que a veces se llaman desde un contexto atómico. Esto puede provocar un pánico en el kernel en algunos escenarios, como la desconexión y reconexión de cables en sistemas vPro. Resuelva esto volviendo a cambiar las llamadas usleep_range a udelay.
