| Subject: CVE-2024-50290: media: cx24116: prevent overflows on SNR calculus |
| |
| Description |
| =========== |
| |
| 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. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
