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...
Affected configurations
• linux linux kernel (>= 6.6 < 6.12.42)
• linux linux kernel (>= 6.13 < 6.15.10)
• linux linux kernel (>= 6.16 < 6.16.1)
