CVE-2006-1368: Linux Kernel: Buffer overflow

CVE-2006-1368 has a CVSS v2 base score of 10.0 (the maximum on that scale) and affects Linux Kernel. Per its scoring, it can be exploited over the network, without authentication. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

Buffer overflow in the USB Gadget RNDIS implementation in the Linux kernel before 2.6.16 allows remote attackers to cause a denial of service (kmalloc'd memory corruption) via a remote NDIS response to OID_GEN_SUPPORTED_LIST, which causes memory to be allocated for the reply data but not the reply structure.

Severity breakdown

CVSS v2.0 10.0: AV:N/AC:L/Au:N/C:C/I:C/A:C

  • Access vector: Network. Exploitable remotely over the network.
  • Access complexity: Low. No special conditions are required.
  • Authentication: None. No authentication is needed.
  • Confidentiality impact: Complete. Total information disclosure.
  • Integrity impact: Complete. Total loss of integrity.
  • Availability impact: Complete. Total shutdown of the component.

Underlying weakness

CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer

The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary.

Affected products

  • Linux Kernel: up to and including 2.6.15
