Detailsinfo

A vulnerability was found in Linux Kernel up to 6.11.7. It has been classified as critical. This affects an unknown function of the component cx24116. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: media: cx24116: prevent overflows on SNR calculus as reported by Coverity, if reading SNR registers fail, a negative number will be returned, causing an underflow when reading SNR registers. Prevent that.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2024-50290 since 10/21/2024. The exploitability is told to be easy. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/02/2025).
