Doc Text:	A flaw was found in the Linux kernel's `atomisp` driver, located in the `staging: media` subsystem. This vulnerability involves the unsafe handling of private Input/Output Control (IOCTL) operations. While specific exploitation details are not provided, the presence of unsafe IOCTL handlers could potentially allow a local attacker to compromise the system, leading to consequences such as information disclosure, denial of service, or privilege escalation.

Description OSIDB Bzimport 2026-05-28 11:02:33 UTC

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.
