Summary
linux, linux-aws, linux-gcp, linux-kvm, linux-oem, linux-raspi2 vulnerabilities
Details

Jann Horn discovered that the vmacache subsystem did not properly handle sequence number overflows, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2018-17182)

It was discovered that the paravirtualization implementation in the Linux kernel did not properly handle some indirect calls, reducing the effectiveness of Spectre v2 mitigations for paravirtual guests. A local attacker could use this to expose sensitive information. (CVE-2018-15594)

It was discovered that microprocessors utilizing speculative execution and prediction of return addresses via Return Stack Buffer (RSB) may allow unauthorized memory reads via sidechannel attacks. An attacker could use this to expose sensitive information. (CVE-2018-15572)

Andy Lutomirski and Mika Penttilä discovered that the KVM implementation in the Linux kernel did not properly check privilege levels when emulating some instructions. An unprivileged attacker in a guest VM could use this to escalate privileges within the guest. (CVE-2018-10853)

It was discovered that a stack-based buffer overflow existed in the iSCSI target implementation of the Linux kernel. A remote attacker could use this to cause a denial of service (system crash). (CVE-2018-14633)

It was discovered that a memory leak existed in the IRDA subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2018-6554)

It was discovered that a use-after-free vulnerability existed in the IRDA implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-6555)

USN 3652-1 added a mitigation for Speculative Store Bypass a.k.a. Spectre Variant 4 (CVE-2018-3639). This update provides the corresponding mitigation for ARM64 processors. Please note that for this mitigation to be effective, an updated firmware for the processor may be required.

A local\nattacker could use this to expose sensitive information. (CVE-2018-15594)\n\nIt was discovered that microprocessors utilizing speculative execution and\nprediction of return addresses via Return Stack Buffer (RSB) may allow\nunauthorized memory reads via sidechannel attacks. An attacker could use\nthis to expose sensitive information. (CVE-2018-15572)\n\nAndy Lutomirski and Mika Penttil\u00e4 discovered that the KVM implementation\nin the Linux kernel did not properly check privilege levels when emulating\nsome instructions. An unprivileged attacker in a guest VM could use this to\nescalate privileges within the guest. (CVE-2018-10853)\n\nIt was discovered that a stack-based buffer overflow existed in the iSCSI\ntarget implementation of the Linux kernel. A remote attacker could use this\nto cause a denial of service (system crash). (CVE-2018-14633)\n\nIt was discovered that a memory leak existed in the IRDA subsystem of the\nLinux kernel.
