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.
