In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov8856: free control handler on error in ov8856_init_controls() The… (CVE-2026-53379)
A vulnerability in the Linux kernel's media i2c driver for the ov8856 camera sensor was resolved. The issue involved the control handler not being freed if adding controls failed during initialization in ov8856_init_controls(). This could lead to resource management issues. The vulnerability has been fixed by adding an error exit label to properly free the control handler on failure.
AI Analysis
Technical Summary
The Linux kernel contained a vulnerability in the media i2c ov8856 driver where the control handler was not freed if adding controls failed in the ov8856_init_controls() function. This improper resource cleanup was addressed by introducing an error exit label that ensures the control handler is freed on error, preventing potential resource leaks.
Potential Impact
The vulnerability could cause resource leaks due to failure to free the control handler on error during initialization. There is no indication of direct exploitation or broader impact such as privilege escalation or denial of service from the provided data.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to properly free the control handler on error in ov8856_init_controls(). Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed; check the vendor or kernel mailing list advisories for the exact fixed versions and update accordingly.
