Description
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").
Affected configurations
• linux linux kernel (>= 6.1.57 < 6.1.114)
• linux linux kernel (>= 6.2 < 6.6.58)
• linux linux kernel (>= 6.7 < 6.11.5)
• linux linux kernel 6.12
