Description Rohit Keshri 2024-02-27 13:39:36 UTC 
In the Linux kernel, the following vulnerability has been resolved:

i2c: Fix a potential use after free

Free the adap structure only after we are done using it.
This patch just moves the put_device() down a bit to avoid the
use after free.

[wsa: added comment to the code, added Fixes tag]
