CVSS: 7.8EPSS: 0%CPEs: 24EXPL: 5CVE-2018-8897 – Microsoft Windows POP/MOV SS Local Privilege Elevation Vulnerability
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') •
CVSS: 7.8EPSS: 0%CPEs: 29EXPL: 0CVE-2018-10675 – kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact
https://notcve.org/view.php?id=CVE-2018-10675
The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls. La función do_get_mempolicy en mm/mempolicy.c en el kernel de Linux, en versiones anteriores a la 4.12.9, permite que los usuarios locales provoquen una denegación de servicio (uso de memoria previamente liberada) o, posiblemente, causen otros impactos no especificados mediante llamadas del sistema manipuladas. The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=73223e4e2e3867ebf033a5a8eb2e5df0158ccc99 http://www.securityfocus.com/bid/104093 https://access.redhat.com/errata/RHSA-2018:2164 https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2018:2785 https://access.redhat.com/errata/RHSA-2018:2791 https://access.redhat.com/errata/RHSA-2018:2924 https://access.redhat.com/errata/RHSA-2018& • CWE-416: Use After Free •
