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...

Information Disclosure

Kernel is vulnerable to information disclosure. The vulnerability exists due to incomplete Spectre-RSB mitigation which allows an attacker to gain access to sensitive information...

CVE-2020-10767

A flaw was found in the Linux kernel before 5.8-rc1 in the 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 loc...

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...

New Noise-Resilient Attack On Intel and AMD CPUs Makes Flush-based Attacks Effective
