CVE-2025-38660

  3. CVE-2025-38660
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...

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: [ceph] parse_longname(): strrchr() espera una cadena terminada en NUL... y parse_longname() no lo garantiza. Por eso usa kmemdup_nul() para construir el argumento de kstrtou64(); el problema es que kstrtou64() no es el único que lo necesita. Simplemente obtenga una copia terminada en NUL de todo el conjunto y listo.
