Denial Of Service (DoS)

kernel is vulnerable to denial of service. The RHSA-2011:1530 kernel update introduced an integer overflow flaw in the Linux kernel. On PowerPC systems, a local, unprivileged user could use this flaw to cause a denial of service...

Denial Of Service (DoS)

The kernel is vulnerable to denial of service DoS.A possible NULL pointer dereference was found in the subsystem used for showing CPU information, as used by CHRP systems on PowerPC architectures. This may have allowed a local unprivileged user to cause a denial of service crash...

Information Disclosure

kernel is vulnerable to information disclosure. The vulnerability exists as a flaw was found in the eHCA driver on PowerPC architectures that allowed a local user to access 60k of physical address space. This address space could contain sensitive information...

Linux kernel KVM Competitive Conditions Issue Vulnerability

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the KVM's of the Linux kernel for PowerPC processors, which stems from the program's failure to properly separate the state of the...

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 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...
