CVE-2026-98005

Name	CVE-2026-98005
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.
