Upgrade SLES:15.4 kernel-default-livepatch to version 5.14.21-150400.24.161.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-livepatch package and not the kernel-default-livepatch package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

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

scsi: target: tcmu: Fix possible page UAF

tcmu_try_get_data_page() looks up pages under cmdr_lock, but it does not take refcount properly and just returns page pointer. When tcmu_try_get_data_page() returns, the returned page may have been freed by tcmu_blocks_release().

We need to get_page() under cmdr_lock to avoid concurrent tcmu_blocks_release().
