Description

btrfs: fix uninitialized pointer free on read_alloc_one_name() error

In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix uninitialized pointer free on read_alloc_one_name() error

The function read_alloc_one_name() does not initialize the name field of

the passed fscrypt_str struct if kmalloc fails to allocate the

corresponding buffer. Thus, it is not guaranteed that

fscrypt_str.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").

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
