CVE-2019-15791

In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfsbtrfsioctlfdreplace installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, whi...

PT-2019-4754

Name of the Vulnerable Software and Affected Versions Linux kernel versions 5.0 and 5.3 Description The issue is related to a non-upstream patch in the Linux kernel, specifically in the shiftfs component. It involves a type conversion error, where the shiftfs btrfs ioctl fd replace function calls...

CVE-2018-14611

An issue was discovered in the btrfs filesystem code in the Linux kernel. A use-after-free is possible in trymergefreespace when mounting a crafted btrfs image due to a lack of chunk type flag checks in btrfscheckchunkvalid in the fs/btrfs/volumes.c function. This could lead to a denial of servic...

Name of the Vulnerable Software and Affected Versions Linux kernel versions 5.0 and 5.3 Description The issue is related to an uncontrolled resource consumption in the shiftfs component of the Linux kernel. Exploitation of this issue may allow an attacker to cause a denial of service. The problem...

CVE-2018-14613

An issue was discovered in the btrfs filesystem code in the Linux kernel. An invalid pointer dereference in ioctlmappage when mounting and operating a crafted btrfs image is due to a lack of block group item validation in checkleafitem in fs/btrfs/tree-checker.c function. This could lead to a...

CVE-2010-2071

The btrfsxattrsetacl function in fs/btrfs/acl.c in btrfs in the Linux kernel 2.6.34 and earlier does not check file ownership before setting an ACL, which allows local users to bypass file permissions by setting arbitrary ACLs, as demonstrated using setfacl...

CVE-2010-1636

The btrfsioctlclone function in fs/btrfs/ioctl.c in the btrfs functionality in the Linux kernel 2.6.29 through 2.6.32, and possibly other versions, does not ensure that a cloned file descriptor has been opened for reading, which allows local users to read sensitive information from a write-only...
