kconfig-hardened-check-master

This is a tool for checking Linux kernel Kconfig option lists against security hardening preferences. The tool is called "kconfig-hardened-check" and is written in Python. It is designed to help users ensure that their Linux systems are properly secured by checking the kernel configuration agains...

Side-channel Attack

kernel is vulnerable to side-channel attack. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory...

kernel: protection of stack pointer against speculative pointer arithmetic can be bypassed to leak content of kernel memory

A flaw was found in the Linux kernel's eBPF verification code. By default, accessing the eBPF verifier is only accessible to privileged users with CAPSYSADMIN. This flaw allows a local user who can insert eBPF instructions, to use the eBPF verifier to abuse a spectre-like flaw and infer all syste...

kernel: protection for sequences of pointer arithmetic operations against speculatively out-of-bounds loads can be bypassed to leak content of kernel memory

A vulnerability was discovered in retrieveptrlimit in kernel/bpf/verifier.c in the Linux kernel mechanism to mitigate speculatively out-of-bounds loads Spectre mitigation. In this flaw a local, special user privileged CAPSYSADMIN BPF program running on affected systems may bypass the protection,...

ASB-A-169505929

In ibprctlset of bugs.c, there is a possible way to re-enable indirect branch speculation due to a permissions bypass. This could lead to local information disclosure via a Spectre v2 attack with no additional execution privileges needed. User interaction is not needed for exploitation...

USN-5092-1: Linux kernel vulnerabilities

Valentina Palmiotti discovered that the iouring subsystem in the Linux kernel could be coerced to free adjacent memory. A local attacker could use this to execute arbitrary code. CVE-2021-41073 Ofek Kirzner, Adam Morrison, Benedict Schlueter, and Piotr Krysiuk discovered that the BPF verifier in...

New SpookJS Attack Bypasses Google Chrome's Site Isolation Protection

A newly discovered side-channel attack demonstrated on modern processors can be weaponized to successfully overcome Site Isolation protections weaved into Google Chrome and Chromium browsers and leak sensitive data in a Spectre-style speculative execution attack. Dubbed "Spook.js" by academics fr...
