In the Linux kernel, the following vulnerability has been resolved:
ceph: avoid putting the realm twice when decoding snaps fails
When decoding the snaps fails it maybe leaving the 'first_realm' and 'realm' pointing to the same snaprealm memory. And then it'll put it twice and could cause random use-after-free, BUG_ON, etc issues.
