CVE-2018-14610

An issue was discovered in the btrfs filesystem code in the Linux kernel. An out-of-bounds access is possible in writeextentbuffer when mounting and operating a crafted btrfs image due to a lack of verification at mount time within the btrfsreadblockgroups in fs/btrfs/extent-tree.c function. This...

CVE-2019-19816

A flaw was found in the implementation of the BTRFS file system code in the Linux kernel. An attacker, who is able to mount a crafted BTRFS filesystem and perform common filesystem operations, can possibly cause an out-of-bounds write to memory. This could lead to memory corruption or privilege...
