Title
media: i2c: alvium: fix critical pointer access in alvium_ctrl_init
Summary
In the Linux kernel, the following vulnerability has been resolved: media: i2c: alvium: fix critical pointer access in alvium_ctrl_init The current implementation of alvium_ctrl_init creates several controls in function alvium_ctrl_init and uses the returned pointer without check. That can cause write access over NULL-pointer for several controls. The reworked code checks the pointers before adding flags.
Severity
No CVSS data available.
