CVE-2019-11833

Priority
Description
fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the
unused memory region in the extent tree block, which might allow local
users to obtain sensitive information by reading uninitialized data in the
filesystem.
Ubuntu-Description
It was discovered that the ext4 file system implementation in the Linux
kernel did not properly zero out memory in some situations. A local
attacker could use this to expose sensitive information (kernel memory).
