CVE-2026-46205: staging: media: atomisp: Disallow all private IOCTLs
Published May 28, 2026
·Updated
In the Linux kernel, the following vulnerability has been resolved:
staging: media: atomisp: Disallow all private IOCTLs
Disallow all private IOCTLs. These aren't quite as safe as one could assume of IOCTL handlers; disable them for now. Instead of removing the code, return in the beginning of the function if cmd is non-zero in order to keep static checkers happy.
