CVE-2019-15918

Priority
Description
An issue was discovered in the Linux kernel before 5.0.10. SMB2_negotiate
in fs/cifs/smb2pdu.c has an out-of-bounds read because data structures are
incompletely updated after a change from smb30 to smb21.
Ubuntu-Description
It was discovered that the SMB networking file system implementation in the
Linux kernel contained a buffer overread. An attacker could use this to
expose sensitive information (kernel memory).
