CVE-2022-50548
media: i2c: hi846: Fix memory leak in hi846_parse_dt()
Description
In the Linux kernel, the following vulnerability has been resolved: media: i2c: hi846: Fix memory leak in hi846_parse_dt() If any of the checks related to the supported link frequencies fail, then the V4L2 fwnode resources don't get released before returning, which leads to a memleak. Fix this by properly freeing the V4L2 fwnode data in a designated label.
