AV:A/AC:L/Au:N/C:C/I:C/A:C
kernel is vulnerable to privilege escalation. The vulnerability exists through a signedness issue found in the Linux kernel’s CIFS (Common Internet File System) implementation. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted.
