Intel Microprocessors 安全漏洞

Intel Microprocessors are microprocessor CPU products from Intel Corporation. A security vulnerability exists in Intel Microprocessors generations 6 through 8, which stems from Spectre's ability to bypass retpoline in the kernel to leak arbitrary data...

ALPINE-CVE-2022-23960

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. Then, cache allocation can allow the attacker to obtai...

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...

Security Bulletin: IBM DataPower Gateway has released a fixpack in response to the vulnerability known as Spectre.

Summary IBM has released the following fixpack for IBM DataPower Gateways in response to CVE-2017-5753. Vulnerability Details CVEID: CVE-2017-5753 Affected Products and Versions IBM DataPower Gateways appliances, versions 7.1.0.0-7.1.0.21, 7.2.0.0-7.2.0.18, 7.5.0.0-7.5.0.12, 7.5.1.0-7.5.1.11,...

An issue was discovered in the Linux kernel through 5.11.x. 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. Specifically for sequences of pointer arithmetic operations the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations.

Intel, ARM, IBM, AMD Processors Vulnerable to New Side-Channel Attacks

It turns out that the root cause behind several previously disclosed speculative execution attacks against modern processors, such as Meltdown and Foreshadow, was misattributed to 'prefetching effect,' resulting in hardware vendors releasing incomplete mitigations and countermeasures. Sharing its...

UBUNTU-CVE-2020-10768

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 threa...
