CVE-2026-74595

CVE-2026-74595 is a Linux kernel vulnerability in the fscrypt subsystem, specifically in fscrypt_ioctl_set_policy(). The function calls inode_owner_or_capable() with &nop_mnt_idmap instead of the idmap of the mount on which the ioctl was issued. On idmapped mounts (e.g., ext4, f2fs), this causes ...

CVE-2026-62313 Incus: Project restriction `restricted.containers.privilege=isolated` bypassable by omitting `security.idmap.isolated`

Incus is a system container and virtual machine manager. Prior to version 7.3.0, project-level enforcement of restricted.containers.privilege=isolated can be trivially bypassed, allowing a user to create a non-isolated shared host idmap container in a project that is configured to forbid them. Th...

CVE-2026-62313

Incus (system container and VM manager) prior to 7.3.0 contains a bypass of the project-level restriction restricted.containers.privilege=isolated. The check only rejects an explicitly set security.idmap.isolated=false or empty value, but does not enforce the restriction when the key is omitted e...
