How to fix?

There is no fixed version for RHEL:10 kernel-debug-devel-matched.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-devel-matched package and not the kernel-debug-devel-matched 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:

net: hsr: fix potential OOB access in supervision frame handling

Ensure the entire TLV header is linearized before access by adding sizeof(struct hsr_sup_tlv) to the pskb_may_pull() calls. Without this, a truncated frame could cause an out-of-bounds access.
