CVE-2026-68225

Estado: RecibidaSin puntuar—

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.
