🛡️ CVE-2026-46205 on Ubuntu — linux
Description
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.
Distribution advisory
This page covers CVE-2026-46205 as tracked by Ubuntu, for the package linux. The fix is available in version 7.0.0-28.28; earlier versions remain affected.
How this vulnerability can be exploited
This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
