Description

In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov02a10: fix endpoint parsing use-after-free The ov02a10_check_hwcfg() function calls fwnode_handle_put(ep) immediately after allocating and parsing the endpoint. However, it subsequently calls fwnode_property_read_u32() using the same 'ep' handle, leading to a potential use-after-free. Additionally, reading the optional 'ovti,mipi-clock-voltage' property used to overwrite the 'ret' variable. If the property was missing, 'ret' would become negative, and this failure code would be incorrectly returned at the end of the function, causing probe to fail entirely. Fix the use-after-free by moving fwnode_property_read_u32() before the endpoint is parsed and freed. Avoid the error leak by not assigning the result of fwnode_property_read_u32() to 'ret'.
