Description OSIDB Bzimport 2025-09-05 18:02:24 UTC

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

platform/x86/amd/hsmp: Ensure sock->metric_tbl_addr is non-NULL

If metric table address is not allocated, accessing metrics_bin will
result in a NULL pointer dereference, so add a check.
