Vulnerability Data

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: don't attempt to schedule hpd_work on headless cards If the card doesn't have display hardware, hpd_work and hpd_lock are left uninitialized which causes BUG when attempting to schedule hpd_work…

more

on runtime PM resume. Fix it by adding headless flag to DRM and skip any hpd if it's set.

prevents

Secure SDLC activities such as static analysis and code review directly prevent use of uninitialized resources while also addressing many other weaknesses.

detects

Security testing in development and acceptance can detect uninitialized resource usage through dynamic analysis and fuzzing.

prevents

Secure development life cycle mandates initialization checks and static analysis that can catch uninitialized resource use.

prevents

Application security requirements can specify mandatory initialization of variables and resources before use.

prevents

Secure system architecture and engineering principles include defensive coding practices that prevent use of uninitialized memory or objects.

prevents

Secure coding standards directly require explicit initialization of all variables and resources, substantially mitigating CWE-908.
