Vulnerability Data

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: initialize damo_filter->list from damos_new_filter() damos_new_filter() is not initializing the list field of newly allocated filter object. However, DAMON sysfs interface and DAMON_RECLAIM are not initializing it after calling damos_new_filter().…

more

As a result, accessing uninitialized memory is possible. Actually, adding multiple DAMOS filters via DAMON sysfs interface caused NULL pointer dereferencing. Initialize the field just after the allocation from damos_new_filter().

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.
