In the Linux kernel, the following vulnerability has been resolved: btrfs: fix uninitialized pointer free on readalloconename() error The function readalloconename() does not initialize the name field of the passed fscryptstr struct if kmalloc fails to allocate the corresponding buffer. Thus, it is not guaranteed that fscryptstr.name is initialized when freeing it. This is a follow-up to the linked patch that fixes the remaining instances of the bug introduced by commit e43eec81c516 ("btrfs: use struct qstr instead of name and namelen pairs").
