CVSS: 8.0EPSS: 0%CPEs: 24EXPL: 0CVE-2018-1087 – Kernel: KVM: error in exception handling leads to wrong debug stack value
https://notcve.org/view.php?id=CVE-2018-1087
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest. kernel KVM en versiones anteriores al kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 y kernel 4.17-rc3 es vulnerable a un error en la forma en la que el hipervisor KVM del kernel de Linux gestiona las excepciones lanzadas tras una operación de cambio de pila mediante instrucciones Mov SS o Pop SS. Durante la operación de cambio de pila, el procesador no lanzó interrupciones y excepciones, sino que las lanza una vez se ha ejecutado la primera instrucción tras el cambio de pila. Un usuario invitado sin privilegios de KVM podría usar este error para provocar el cierre inesperado del guest o escalar sus privilegios en el guest. • http://www.openwall.com/lists/oss-security/2018/05/08/5 http://www.securityfocus.com/bid/104127 http://www.securitytracker.com/id/1040862 https://access.redhat.com/errata/RHSA-2018:1318 https://access.redhat.com/errata/RHSA-2018:1345 https://access.redhat.com/errata/RHSA-2018:1347 https://access.redhat.com/errata/RHSA-2018:1348 https://access.redhat.com/errata/RHSA-2018:1355 https://access.redhat.com/errata/RHSA-2018:1524 https://access.redhat.com/security/vulnerabili • CWE-250: Execution with Unnecessary Privileges •
CVSS: 7.8EPSS: 0%CPEs: 24EXPL: 4CVE-2018-8897 – Microsoft Windows - 'POP/MOV SS' Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-8897
A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. • https://www.exploit-db.com/exploits/44697 https://www.exploit-db.com/exploits/45024 https://github.com/can1357/CVE-2018-8897 https://github.com/nmulasmajic/CVE-2018-8897 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d8ba61ba58c88d5207c1ba2f7d9a2280e7d03be9 http://openwall.com/lists/oss-security/2018/05/08/1 http://openwall.com/lists/oss-security/2018/05/08/4 http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20190921-01-debug-en http: • CWE-250: Execution with Unnecessary Privileges CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
