CVE-2024-50234

Summary

CVE-2024-50234: A vulnerability in the Linux kernel's iwl4965 driver causes the wifi interface to fail upon resume from hibernation. The issue arises due to a stale interrupt that isn't cleared before interrupts are enabled, resulting in a race condition. During resume, the system attempts to bring things back up, while the restart work from the interrupt handler tries to bring things down, eventually causing the whole system to crash. The issue has been resolved by clearing out any stale interrupts before interrupts get enabled during resume. The debug log shows various messages related to the wifi interface, including failed attempts to bring it back up, indicating the presence of this vulnerability.
