kernel: powerpc/64s: Fix unrecoverable MCE calling async handler from NMI

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Fix unrecoverable MCE calling async handler from NMI The machine check handler is not considered NMI on 64s. The early handler is the true NMI handler, and then it schedules the machinecheckexception handler to run...

kernel: powerpc/iommu: Fix notifiers being shared by PCI and VIO buses

A slab-out-of-bounds read vulnerability was found in the Linux kernel's PowerPC IOMMU code. The failiommusetup function registers the same notifierblock structure to both PCI and VIO buses. Since notifierblock is a linked list node, this causes notifiers registered to one bus type to also apply t...

The POLY1305 MAC (message authentication code) implementation contains a bug that might corrupt the internal state of applications running on PowerPC CPU based platforms

OpenSSL contains an issue in the POLY1305 MAC message authentication code implementation that might result in a corrupted internal application state. This flaw is only exploitable on PowerPC CPU based platforms if the CPU provides vector instructions PowerISA 2.07. The impact of the corrupted...
