CVE-2026-98005
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.
