Vulnerability Details

CVEID: CVE-2017-5753

    DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow
    a local authenticated attacker to obtain sensitive information, caused by a
    bounds check bypass in the CPU speculative branch instruction execution
    feature. By conducting targeted cache side-channel attacks, an attacker
    could exploit this vulnerability to cross the syscall boundary and read data
    from the CPU virtual memory.

    CVSS Base Score: 7.3

    CVSS Temporal Score: See
    https://exchange.xforce.ibmcloud.com/vulnerabilities/137052 for the current
    score

    CVSS Environmental Score*: Undefined

    CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N)

CVEID: CVE-2017-5754

    DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow
    a local authenticated attacker to obtain sensitive information, caused by a
    rogue data cache load in the CPU speculative branch instruction execution
    feature. By conducting targeted cache side-channel attacks, an attacker
    could exploit this vulnerability to cause the CPU to read kernel memory from
    userspace before the permission check for accessing an address is performed.

    CVSS Base Score: 5.6

    CVSS Temporal Score: See
    https://exchange.xforce.ibmcloud.com/vulnerabilities/137053 for the current
    score

    CVSS Environmental Score*: Undefined

    CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N)

CVEID: CVE-2017-5715

    DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow
    a local authenticated attacker to obtain sensitive information, caused by a
    branch target injection in the CPU speculative branch instruction execution
    feature. By conducting targeted cache side-channel attacks, an attacker
    could exploit this vulnerability to leak memory contents into a CPU cache
    and read host kernel memory.

    CVSS Base Score: 6.5

    CVSS Temporal Score: See
    https://exchange.xforce.ibmcloud.com/vulnerabilities/137054 for the current
    score
