n the Linux kernel, the following vulnerability has been resolved: btrfs: fix ulist leaks in error paths of qgroup self tests In the test_no_shared_qgroup() and test_multiple_refs() qgroup self tests, if we fail to add the tree ref, remove the extent item or remove the extent ref, we are returning from the test function without freeing the "old_roots" ulist that was allocated by the previous calls to btrfs_find_all_roots(). Fix that by calling ulist_free() before returning.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: btrfs: se corrigen fugas de ulist en las rutas de error de las autopruebas de qgroup. En las autopruebas de qgroup test_no_shared_qgroup() y test_multiple_refs(), si no se añade la referencia del árbol, se elimina el elemento de extensión o se elimina la referencia de extensión, se regresa de la función de prueba sin liberar la ulist "old_roots" asignada por las llamadas anteriores a btrfs_find_all_roots(). Se puede solucionar llamando a ulist_free() antes de regresar.
