Vulnerability fixed in ARM, AMD and Intel processors

Researchers at VU Amsterdam have found a new variant of the Spectre vulnerability. The researchers have dubbed the attack Branch History Injection. Previous mitigation for Spectre v2 is not sufficient to fully fix the vulnerability, according to the researchers. According to the researchers, this...

New Exploit Bypasses Existing Spectre-V2 Mitigations in Intel, AMD, Arm CPUs

Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm, and stage speculative execution attacks such as Spectre to leak sensitive information from host memory. Attacks like Spectre are designed to bre...

CVE-2021-26401

A flaw was found in hw. The speculative execution window of AMD LFENCE/JMP mitigation MITIGATION V2-2 may be large enough to be exploited on AMD CPUs. Mitigation AMD recommends mitigation that uses generic retpoline...

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,...

The vulnerability of AMD’s microprogrammed software for processors lies in the speculative execution of read and write operations that access memory using invalid non- canonical addresses. This allows a hacker to exploit the vulnerability to gain access to information about the CPU’s address space.

The vulnerability of AMD’s microprogramming software is related to speculative operations for reading and writing data to memory, involving the use of non- canonical addresses. Exploiting this vulnerability can allow an attacker to gain access to information about the CPU’s address space, by usin...
