CVE-2018-13098

An issue was discovered in the F2FS filesystem code in the Linux kernel in fs/f2fs/inode.c. A denial of service due to a slab out-of-bounds read can occur for a crafted f2fs filesystem image in which FIEXTRAATTR is set in an inode...

CVE-2019-19767

A use-after-free flaw was found in the Linux kernel’s ext4 file system functionality when the user mount ext4 partition, with the usage of an additional debug parameter is defining an extra inode size. If this parameter has a non zero value, this flaw allows a local user to crash the system when...

kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members

A vulnerability was found in the fs/inode.c:inodeinitowner function logic of the LInux kernel that allows local users to create files with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group an...

Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel (AWS) vulnerabilities (USN-4118-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4118-1 advisory. It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow vulnerability. A local attacker could...

USN-4118-1 linux-aws vulnerabilities

It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service. CVE-2018-13053 Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly track...

UBUNTU-CVE-2019-15538

An issue was discovered in xfssetattrnonsize in fs/xfs/xfsiops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfssetattrnonsize is failing to unlock the ILOCK after the xfsqmvopchownreserve call fails. This is primarily a local...

Denial Of Service (DoS)

kernel is vulnerable to denial of servie DoS. The vulnerability exists through NULL pointer dereference in fs/xfs/libxfs/xfsinodebuf.c...

kernel: NULL pointer dereference in lookup_slow function

An issue was discovered in the XFS filesystem in fs/xfs/xfsicache.c in the Linux kernel. There is a NULL pointer dereference leading to a system panic in lookupslow on a NULL inode-iops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that...

kernel: NULL pointer dereference in fs/xfs/libxfs/xfs_inode_buf.c

An issue was discovered in the XFS filesystem in fs/xfs/libxfs/xfsinodebuf.c in the Linux kernel. A denial of service due to the NULL pointer dereference can occur for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork...

kernel: NULL pointer dereference in xfs_da_shrink_inode function

An issue was discovered in the XFS filesystem in fs/xfs/libxfs/xfsattrleaf.c in the Linux kernel. A NULL pointer dereference may occur for a corrupted xfs image after xfsdashrinkinode is called with a NULL bp. This can lead to a system crash and a denial of service...
