CVE-2021-47429

CVE-2021-47429 – Linux kernel (powerpc/64s): The issue occurs when an unrecoverable MCE is handled in NMI context, where the true NMI handling path could lead to calling an async MCE handler and corrupt IRQ state. The fix introduces separate _async and NMI-specific machine_check_exception handler...

CVE-2024-26674

In the Linux kernel, the following vulnerability has been resolved: x86/lib: Revert to ASMEXTABLEUA for get,putuser fixups During memory error injection test on kernels = v6.4, the kernel panics like below.
