## Description

In the Linux kernel, the following vulnerability has been resolved:  erofs: delimit inode_share cache key components  Previously, inode_share keys were encoded as follows:    fingerprint || domain_id  It would be better to have a separator between the fingerprint and domain ID so that the fingerprint won't be parsed as part of a domain ID.  Change the key encoding as follows:    domain_id || '\0' || fingerprint  Since domain_id is a NUL-terminated string, this makes the in-memory key indices unambiguous.
