UBUNTU-CVE-2021-47429

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...

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-2021-47428

CVE-2021-47428 is a Linux kernel issue in powerpc/64s emergency stack handling where the emergency path could jump into a non-trivial macro path; the fix avoids numeric labels when jumping over macros. Several vendor/MiracleUnity advisories reference the same patch and include the same descriptio...

CVE-2021-47350 powerpc/mm: Fix lockup on kernel exec fault

In the Linux kernel, the following vulnerability has been resolved: powerpc/mm: Fix lockup on kernel exec fault The powerpc kernel is not prepared to handle exec faults from kernel. Especially, the function isexecfault will return 'false' when an exec fault is taken by kernel, because the check i...

CVE-2021-47350

Affected software: Linux kernel on PowerPC. The issue stems from is_exec_fault() returning false for exec faults taken by the kernel, causing set_access_flags_filter() not to set PAGE_EXEC and leading to a perpetual minor exec fault. Root cause traced through a sequence of commits (notably d7df24...

CVE-2021-47317

CVE-2021-47317 concerns the Linux kernel’s powerpc/bpf component. A commit changed BPF_XADD to BPF_ATOMIC and introduced a mechanism to distinguish instructions by the immediate field. JITs were updated to enforce that only certain immediates (e.g., BPF_ADD) are allowed, but the powerpc64 JIT che...
