kernel: powerpc: local user can read vector registers of other users' processes via an interrupt

A flaw in the Linux kernel on the PowerPC platform, was found where a local user can read vector registers of other user processes during a hardware interrupt. An attacker must start a transaction when the FPU operation begins or there is no leakage. Vector registers will become corrupted with...

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...

Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel vulnerabilities (USN-4318-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4318-1 advisory.

USN-4318-1 linux, linux-hwe vulnerabilities

Al Viro discovered that the vfs layer in the Linux kernel contained a use- after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly expose sensitive information kernel memory. CVE-2020-8428 Gustavo Romero and Paul Mackerras discovered that th...

UBUNTU-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...

CVE-2019-18660

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...

CVE-2019-12614

A flaw was found in the way Linux kernel's Dynamic Logical Partitioning DLPAR functionality on PowerPC systems handled low memory conditions on device discovery. An attacker who can change the LPAR configuration and incur low memory conditions at the same time could use this flaw to crash the...

Denial Of Service (DoS)

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 SLES12 Security Update : glibc (SUSE-SU-2020:0832-1)

This update for glibc fixes the following issues : CVE-2020-1752: Fixed a use after free in glob which could have allowed a local attacker to create a specially crafted path that, when processed by the glob function, could potentially have led to arbitrary code execution bsc1167631. CVE-2020-1751...

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...
