How to fix?

There is no fixed version for RHEL:10 kernel-rt-64k-modules.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-modules package and not the kernel-rt-64k-modules package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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

iommu/intel: Fix out-of-bounds memset in dmar_latency_disable()

dmar_latency_disable() intends to zero out only the single latency_statistic entry for the given type, but the memset size was computed as sizeof(*lstat) * DMAR_LATENCY_NUM, which clears the entire array starting from &lstat[type].

When type > 0, this writes beyond the end of the allocated array, corrupting adjacent memory.

Fix by using sizeof(*lstat) to clear only the target entry.
