Detailsinfo

A vulnerability was found in Linux Kernel up to 6.5.4. It has been rated as critical. Affected by this issue is the function qt1010_init of the file drivers/media/tuners/qt1010.c of the component media. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: media: tuners: qt1010: replace BUG_ON with a regular error BUG_ON is unnecessary here, and in addition it confuses smatch. Replacing this with an error return help resolve this smatch warning: drivers/media/tuners/qt1010.c:350 qt1010_init() error: buffer overflow 'i2c_data' 34 <= 34
