CVE-2017-15921 — Watchdogdevelopment Anti-Malware security vulnerability
High
CVSS 7.5
In Watchdog Anti-Malware 2.74.186.150 and Online Security Pro 2.74.186.150, the zam32.sys driver contains a NULL pointer dereference vulnerability that gets triggered when sending an operation to ioctl 0x80002010. This is due to the input buffer being NULL or the input buffer size being 0 as they are not validated.

Matched remediation archetype
Buffer bounds, memory safety, and memory corruption
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
- Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
- Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.
Remediate safely
- Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
- Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
- Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
