NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-perf package and not the python3-perf package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:9 relevant fixed versions and status.

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

dlm: validate length in dlm_search_rsb_tree

The len parameter in dlm_dump_rsb_name() is not validated and comes from network messages. When it exceeds DLM_RESNAME_MAXLEN, it can cause out-of-bounds write in dlm_search_rsb_tree().

Add length validation to prevent potential buffer overflow.
