NULL Pointer Dereference Affecting kernel-source-coco package, versions <6.4.0-15061.21.coco15sp6.1
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

NewCVE-2025-38152 (opens in a new tab)How to fix?
Upgrade SLES:15.6 kernel-source-coco to version 6.4.0-15061.21.coco15sp6.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-source-coco package and not the kernel-source-coco 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:
remoteproc: core: Clear table_sz when rproc_shutdown
There is case as below could trigger kernel dump: Use U-Boot to start remote processor(rproc) with resource table published to a fixed address by rproc. After Kernel boots up, stop the rproc, load a new firmware which doesn't have resource table ,and start rproc.
When starting rproc with a firmware not have resource table,
memcpy(loaded_table, rproc->cached_table, rproc->table_sz) will
trigger dump, because rproc->cache_table is set to NULL during the last
stop operation, but rproc->table_sz is still valid.
This issue is found on i.MX8MP and i.MX9.
