Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: btrfs: fixed a race condition between direct IO writes and fsync operations when using the same file descriptor. If we have two threads that use the same file descriptor, and one of them performs direct IO writes while the other...

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. When handling atomic direct I/O DIO operations, if a bio a data structure representing I/O requests is built with a size mismatch and subsequently rejected, the kernel's error handling path fails to release the associated memory pages. This...
