Vulnerability of functions __ext4_iget() (fs/ext4/inode.c) and swap_inode_boot_loader() (fs/ext4/ioctl.c) in the Ext4 file system of the Linux operating system, which allows a hacker to trigger a service failure

The vulnerability of the ext4iget function fs/ext4/inode.c and the swapinodebootloader function fs/ext4/ioctl.c in the Ext4 file system of the Linux operating system is related to insufficient handling of exceptional conditions. Exploiting this vulnerability can allow an attacker to cause a servi...

CVE-2026-74605

A flaw was found in the Linux kernel's eventfs component. This vulnerability allows a local attacker to cause a system crash or other unpredictable behavior due to a race condition during the freeing of an eventfs inode. The issue stems from improper synchronization when iterating over a specific...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ntfs: Avoid self-deadlock during inode eviction.
