kernel: ext4: fix use-after-free in ext4_orphan_cleanup

A use-after-free vulnerability was found in the ext4 filesystem's orphan inode cleanup routine in the Linux kernel. When ext4inodeattachjinode fails with -ENOMEM during orphan cleanup at mount time, the error is not properly propagated. The inode is freed via iput, but the orphan list still...

kernel: Linux kernel: Memory corruption in Squashfs due to incorrect block size calculation

A flaw was found in the Linux kernel's Squashfs filesystem. A local attacker can exploit this vulnerability by simultaneously mounting a Squashfs filesystem and issuing a specific input/output control ioctl command. This can lead to an incorrect block size calculation, causing a shift-out-of-boun...

FreeBSD : FreeBSD -- Jail chroot escape via fd exchange with a different jail (a88f5b2d-11e9-11f1-8148-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the a88f5b2d-11e9-11f1-8148-bc241121aa0a advisory. If two sibling jails are restricted to separate filesystem trees, which is to say that neither of the t...

Linux Kernel 7.x Safe Verification of XFS Scrub ioctl Support

This tool provides a safe and non-exploitative way to verify whether a mount point uses the XFS file system and whether the system kernel supports the ioctl interface for XFS metadata cleanup XFSIOCSCRUBMETADATA. The tool performs verification of the file system type to confirm it is XFS, safely...
