UBUNTU-CVE-2026-80930: Medium severity ubuntu/linux vulnerability

Published Sep 11, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved: tpm: tpmi2cnuvoton: disable IRQ on wait timeout i2cnuvotonwaitforstat() enables the IRQ before waiting for the interrupt handler to report a status change. If the wait times out, or is interrupted before the handler runs, the function returns without balancing the enableirq() call. Disable the IRQ before leaving the failed wait path. Also preserve an interrupted wait's original error code instead of converting it to -ETIMEDOUT inside the helper.
