Impact
In the Linux kernel video driver vidtv, two functions previously copied their input structures by value, which led to Microsoft Sanitizer (MSAN) reporting uninitialized‑value warnings. This change replaces the value copies with const pointers, eliminating the unnecessary stack copy and its MSAN shadow data. Although the patch modifies function parameters, it is inferred from the description that the control flow or behavior of the driver is not altered, and no new execution paths are introduced.
Affected Systems
All mainline Linux kernels that incorporate the vidtv driver before the inclusion of this patch are affected. The patch does not target a particular vendor's distribution and therefore applies broadly to any kernel build using the affected driver code. Version information is not provided, so any kernel older than the commit that changes the function signatures should be identified and updated.
Risk and Exploitability
The EPSS score is less than 1 % and the vulnerability is not listed in CISA KEV, indicating a very low probability of exploitation. Because the issue only causes development‑time diagnostics and does not compromise confidentiality, integrity, or availability, the overall security risk is effectively negligible.
