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:
i3c: master: mipi-i3c-hci: Fix a kernel panic for accessing DAT_data.
The i3c_master_bus_init function may attach the I2C devices before the
I3C bus initialization. In this flow, the DAT alloc_entry`` will be used before the DAT init. Additionally, if the i3c_master_bus_initfails, the DATcleanupwill execute before the device is detached, which will execue DATfree_entry` function. The above scenario can cause the driver
to use DAT_data when it is NULL.
