In the Linux kernel, the following vulnerability has been resolved: powerpc: Avoid nmienter/nmiexit in real mode interrupt. nmienter/nmiexit touches per cpu variables which can lead to kernel crash when invoked during real mode interrupt handling e.g. early HMI/MCE interrupt handler if percpu...
kernel: powerpc/imc-pmu: Add a null pointer check in update_events_in_group()
In the Linux kernel, the following vulnerability has been resolved: powerpc/imc-pmu: Add a null pointer check in updateeventsingroup kasprintf returns a pointer to dynamically allocated memory which can be NULL upon failure...
SUSE CVE-2021-47350
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...

SUSE CVE-2011-4611
Integer overflow in the perfeventinterrupt function in arch/powerpc/kernel/perfevent.c in the Linux kernel before 2.6.39 on powerpc platforms allows local users to cause a denial of service unhandled performance monitor exception via vectors that trigger certain outcomes of performance events...
SUSE CVE-2016-5828
The startthread function in arch/powerpc/kernel/process.c in the Linux kernel through 4.6.3 on powerpc platforms mishandles transactional state, which allows local users to cause a denial of service invalid process state or TM Bad Thing exception, and system crash or possibly have unspecified oth...

Уязвимость функции tm recheckpoint модуля arch/powerpc/kernel/tm.S поддержки платформы PowerPC ядра операционной системы Linux связана с переполнением буфера на основе стека. Эксплуатация уязвимости может позволить нарушителю вызвать отказ в обслуживании...
CVE-2021-43056
An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3shvrmhandlers.S implementation bug in the handling of the SRR1 register values...
kernel: powerpc: KVM guest OS users can cause host OS memory corruption
A flaw was found on the Linux kernel. On the PowerPC platform, the KVM guest allows the OS users to cause host OS memory corruption via rtasargs.nargs. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...

AZL-6579 CVE-2021-37576 affecting package kernel for versions less than 5.10.78.1-1
arch/powerpc/kvm/book3srtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtasargs.nargs, aka CID-f62f3c20647e...
kernel: powerpc: guest can cause DoS on POWER9 KVM hosts
A flaw was found in the way Linux kernel running on the Power9 processor saves and restores its registers while going in and coming out of an idle state. The issue occurs when a guest kernel has Kernel Userspace Address Protection KUAP feature enabled. The idlebook3s function does not save and...
kernel: denial of service in arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c via sigreturn() system call
A flaw was found in the PowerPc platform, where the kernel will panic if the transactional memory is disabled. An attacker could use this flaw to panic the system by constructing a signal context through the transactional memory MSR bits set...
The vulnerability in the arch/powerpc/kernel/process.c component of the Linux operating system allows a attacker to compromise the confidentiality and accessibility of protected information.
The vulnerability in the arch/powerpc/kernel/process.c component of the Linux operating system’s kernel PowerPC microprocessor architecture is related to the lack of protection for service data. Exploiting this vulnerability allows an attacker to compromise the confidentiality and accessibility o...
CVE-2020-11669
An issue was discovered in the Linux kernel before 5.2 on the powerpc platform. arch/powerpc/kernel/idlebook3s.S does not have save/restore functionality for PNVPOWERSAVEAMR, PNVPOWERSAVEUAMOR, and PNVPOWERSAVEAMOR, aka CID-53a712bae5dd...
kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure
A flaw was found in the way the Linux kernel implemented a software flush of the Count Cache indirect branch cache and Link Return Address Stack on the PowerPC platform. The flushing of these structures helps to prevent SpectreRSB like attacks which may leak information from one user process to...
kernel: powerpc: local user can read vector registers of other users' processes via a Facility Unavailable exception
A flaw in the Linux kernel on the PowerPC platform, was found where a local user can read vector registers of other user processes via a Facility Unavailable exception. An attacker must start a transaction when the FPU operation begins or there is no leakage. Vector registers will become corrupte...
