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...
RHEL 6 : kernel (RHSA-2020:2933)
The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2020:2933 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: powerpc: incomplete Spectre-RSB...

CVE-2020-10767
A flaw was found in the Linux kernel’s implementation of the Enhanced IBPB Indirect Branch Prediction Barrier. The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation IBRS is available. This flaw allows a local attacker to perfo...
CVE-2020-10768
A flaw was found in the prctl function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to...
