CVE-2026-68253 in Linux
Riassunto
di MITRE • 10/08/2026
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/hdcp: check streams[] bounds before overflow
The data->streams[] overflow check is done after the buffer overflow has
already happened. Move the overflow check before the write.
Side note, emitting a warning splat with a backtrace might be overkill here, but prefer not changing the behaviour other than not doing the overrun.
Discovered using AI-assisted static analysis confirmed by Intel Product Security.
(cherry picked from commit 9284ab3b6e776c315883ac2611283d263c9460fd)
