Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> e1000e: change usleep_range to udelay in PHY mdic access<br /> <br /> This is a partial revert of commit 6dbdd4de0362 ("e1000e: Workaround<br /> for sporadic MDI error on Meteor Lake systems"). The referenced commit<br /> used usleep_range inside the PHY access routines, which are sometimes<br /> called from an atomic context. This can lead to a kernel panic in some<br /> scenarios, such as cable disconnection and reconnection on vPro systems.<br /> <br /> Solve this by changing the usleep_range calls back to udelay.
