Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.14.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES.
See How to fix? for SLES:15.6 relevant fixed versions and status.
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.
