CVE-2026-93082

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the arm scmi firmware component where the mailbox chan setup() function fails to properly release resources. When the function requests an additional P2A (Processor-to-Application) receiver channel after successfully acquiring the primary P2A channel, a failure in the subsequent request causes the function to return immediately. This leaves the primary channel allocated, which can result in the channel remaining busy during subsequent probe attempts or other setup failures.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
