SUSE CVE-2017-1000255

On Linux running on PowerPC hardware Power8 or later a user process can craft a signal frame and then do a sigreturn so that the kernel will take an exception interrupt, and use the r1 value from the signal frame as the kernel stack pointer. As part of the exception entry the content of the signa...

SUSE CVE-2018-1091

In the flushtmregstothread function in arch/powerpc/kernel/ptrace.c in the Linux kernel before 4.13.5, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory TM...

SUSE CVE-2018-6551

The malloc implementation in the GNU C Library aka glibc or libc6, from version 2.24 to 2.26 on powerpc, and only in version 2.26 on i386, did not properly handle malloc calls with arguments close to SIZEMAX and could return a pointer to a heap region that is smaller than requested, eventually...

SUSE CVE-2019-12614

An issue was discovered in dlparparseccproperty in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop-name, which might allow an attacker to cause a denial of service NULL pointer dereference and system crash...

SUSE CVE-2019-12817

arch/powerpc/mm/mmucontextbook3s64.c in the Linux kernel before 5.1.15 for powerpc has a bug where unrelated processes may be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB. Only a subset of powerpc systems are affected...

SUSE CVE-2019-13648

In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service TM Bad Thing exception and system crash via a sigreturn system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal32.c...

SUSE CVE-2019-15031

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction via the hardware transactional memory instruction tbegin and then accesses vector registers...

SUSE CVE-2019-15030

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction via the hardware transactional memory instruction tbegin and then...

SUSE CVE-2019-18660

The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry64.S and arch/powerpc/kernel/security.c...

SUSE CVE-2020-1751

An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution. The highest...

SUSE CVE-2020-8834

KVM in the Linux kernel on Power8 processors has a conflicting use of HSTATEHOSTR1 to store r1 state in kvmppchventry plus in kvmppcsave,restoretm, leading to a stack corruption. Because of this, an attacker with the ability run code in kernel space of a guest VM can cause the host kernel to pani...

SUSE 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...

SUSE CVE-2021-37576

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...

SUSE CVE-2021-38200

arch/powerpc/perf/core-book3s.c in the Linux kernel before 5.12.13, on systems with perfeventparanoid=-1 and no specific PMU driver support registered, allows local users to cause a denial of service perfinstructionpointer NULL pointer dereference and OOPS via a "perf record" command...

SUSE 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...

SUSE CVE-2022-32981

An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER aka PEEKUSR and POKEUSR when accessing floating point registers...
