K65292036: Linux kernel vulnerability CVE-2019-15791
Security Advisory Description 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...
SUSE 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...
SUSE CVE-2010-2537
The btrfsioctlclone function in fs/btrfs/ioctl.c in the Linux kernel before 2.6.35 allows local users to overwrite an append-only file via a 1 BTRFSIOCCLONE or 2 BTRFSIOCCLONERANGE ioctl call that specifies this file as a donor...

SUSE CVE-2012-5375
The CRC32C feature in the Btrfs implementation in the Linux kernel before 3.8-rc1 allows local users to cause a denial of service prevention of file creation by leveraging the ability to write to a directory important to the victim, and creating a file with a crafted name that is associated with ...
SUSE CVE-2014-9710
The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations 1 during an xattr-replacement time...
