CWE-823
AllowedUse of Out-of-range Pointer Offset
Abstraction: Base · Status: Incomplete
The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.
195 vulnerabilities reference this CWE, most recent first.

GHSA-VCHC-7PH8-GWCP
Vulnerability from github – Published: 2026-01-22 18:30 – Updated: 2026-01-22 18:30VB-Audio Voicemeeter, Voicemeeter Banana, and Voicemeeter Potato (versions ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 and earlier, respectively), as well as VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a vulnerability in their virtual audio drivers (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys, and vbaudio_vmvaio3*.sys). The drivers allocate non-paged pool and map it into user space, where a length value associated with the allocation is exposed and can be modified by an unprivileged local attacker. On subsequent IOCTL handling, the corrupted length is used directly as the IoAllocateMdl length argument without adequate integrity checks before building and mapping the MDL, which can cause a kernel crash (BSoD), typically PAGE_FAULT_IN_NONPAGED_AREA. This flaw allows a local user to trigger a denial-of-service on affected Windows systems.

The vulnerability is due to insufficient input validation of DECnet traffic that is received by an affected device. An attacker could exploit this vulnerability by sending DECnet traffic to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

CAPEC-129: Pointer Manipulation
This attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.
