CVE-2025-38660

MEDIUM

Linux Kernel - Denial of Service via Non-NUL-Terminated String in parse_longname()

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: [ceph] parse_longname(): strrchr() expects NUL-terminated string ... and parse_longname() is not guaranteed that. That's the reason why it uses kmemdup_nul() to build the argument for kstrtou64(); the problem is, kstrtou64() is not the only thing that need it. Just get a NUL-terminated copy of the entire thing and be done with that...
