CVE-2026-45992
Published: May 27, 2026· Updated: Jun 1, 2026
Official Description
In the Linux kernel, the following vulnerability has been resolved:
ALSA: caiaq: Fix potentially leftover ep1_in_urb at error path
The previous fix for handling the error from setup_card() missed that
an internal URB cdev->ep1_in_urb might have been already submitted
beforehand. In the normal case, this URB gets killed at the
disconnection, but in the error path, we didn't do it, hence there can
be a potential leak.
Fix it in the error path for setup_card(), too.
Technical Analysis
CVE-2026-45992 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
