Exploit for Observable Discrepancy in Intel Atom_C

PoC exploit for CVE-2017-5753 and CVE-2017-5715, variants of the Spectre attack. The target product/service is the CPU, specifically the x86 architecture. The vulnerability class/vector is speculative execution, allowing an attacker to trick error-free programs into leaking their secrets. The...

Oracle Linux 7 : Unbreakable Enterprise kernel (ELSA-2020-5885)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5885 advisory. - ext4: fix potential negative array index in dosplit Eric Sandeen Orabug: 31895330 CVE-2020-14314 - mm/hugetlb: fix a race between hugetlb sysctl...

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 local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality.

A flaw was found in the Linux Kernel before 5.8-rc1 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 confidentiality.
