SUSE CVE-2015-8845

The tmreclaimthread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tmreclaim call, which allows local users to cause a denial of service TM Bad Thing exception and panic via a...

SUSE CVE-2016-5412

arch/powerpc/kvm/book3shvrmhandlers.S in the Linux kernel through 4.7 on PowerPC platforms, when CONFIGKVMBOOK3S64HV is enabled, allows guest OS users to cause a denial of service host OS infinite loop by making a HCEDE hypercall during the existence of a suspended transaction...

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...

SUSE CVE-2017-15306

The kvmvmioctlcheckextension function in arch/powerpc/kvm/powerpc.c in the Linux kernel before 4.13.11 allows local users to cause a denial of service NULL pointer dereference and system crash via a KVMCHECKEXTENSION KVMCAPPPCHTM ioctl call to /dev/kvm...

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-2019-15030

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-2019-15031

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-2019-18660

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...
