CVE-2026-72315

A flaw was found in the Linux kernel's SMB client cifs. This issue occurs due to a delayed release of dentry reference counts during direct I/O DIO operations. When a file system is unmounted while these operations are still pending, it can lead to a "busy dentry" warning. This prevents the...

CVE-2026-72370

A flaw was found in the Linux kernel's iomap subsystem.
