The vulnerability of the XFS file system implementation in Linux operating systems allows a attacker to trigger a service failure.
The vulnerability of the XFS file system implementation in Linux operating systems is related to an improper limitation on buffers for downloaded data. Exploiting this vulnerability can allow an attacker to cause a service failure...
CVE-2020-14385
A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is...
Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel vulnerabilities (USN-4485-1)
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-4485-1 advisory. Timothy Michaud discovered that the i915 graphics driver in the Linux kernel did not properly validate user memory locations for the...
USN-4465-1: linux kernel vulnerabilities
It was discovered that the XFS file system implementation in the Linux kernel did not properly validate meta data in some circumstances. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. CVE-2020-12655 It was discovered that the...

The vulnerability of the xfs_agf_verify function in the XFS file system of Linux operating systems allows a attacker to cause a service failure.
The vulnerability of the xfsagfverify function in the XFS file system of Linux operating systems is related to incorrect input validation. Exploiting this vulnerability can allow an attacker to cause a service failure by synchronizing a specially created file with the metadata of the mounted XFS...
DEBIAN-CVE-2020-12655
An issue was discovered in xfsagfverify in fs/xfs/libxfs/xfsalloc.c in the Linux kernel through 5.6.10. Attackers may trigger a sync of excessive duration via an XFS v5 image with crafted metadata, aka CID-d0c7feaf8767...
Arbitrary Code Execution
kernel is vulnerable to arbitrary code execution. A buffer overflow flaw was found in the way the Linux kernel's XFS file system implementation handled links with overly long path names. A local, unprivileged user could use this flaw to cause a denial of service or escalate their privileges by...
Authorization Bypass
kernel is vulnerable to authorization bypass. A flaw was found in the Linux kernel's XFS file system implementation. The file handle lookup could return an invalid inode as valid. If an XFS file system was mounted via NFS Network File System, a local attacker could access stale data or overwrite...
Information Disclosure
kernel is vulnerable to information disclosure. A flaw was found in the handling of the SWAPEXT IOCTL in the Linux kernel XFS file system implementation. A local user could use this flaw to read write-only files, that they do not own, on an XFS file system. This could lead to unintended informati...
