CVSS: 7.2EPSS: 0%CPEs: 3EXPL: 0CVE-2017-17558 – kernel: Unallocated memory access by malicious USB device via bNumInterfaces overflow
https://notcve.org/view.php?id=CVE-2017-17558
The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.

Esto permite que usuarios locales provoquen una denegación de servicio (acceso de escritura fuera de límites) o, posiblemente, tengan otro tipo de impacto sin especificar mediante un dispositivo USB manipulado.

CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 0CVE-2017-1000410 – kernel: Stack information leak in the EFS element
https://notcve.org/view.php?id=CVE-2017-1000410
The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. • http://seclists.org/oss-sec/2017/q4/357 http://www.securityfocus.com/bid/102101 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2018:1130 https://access.redhat.com/errata/RHSA-2018:1170 https://access.redhat.com/errata/RHSA-2018:1319 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 4.7EPSS: 0%CPEs: 1EXPL: 0CVE-2017-17449 – kernel: Missing namespace check in net/netlink/af_netlink.c allows for network monitors to observe systemwide activity
https://notcve.org/view.php?id=CVE-2017-17449
The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system.

CVSS: 7.0EPSS: 0%CPEs: 9EXPL: 4CVE-2017-1000405 – Linux Kernel - 'The Huge Dirty Cow' Overwriting The Huge Zero Page
https://notcve.org/view.php?id=CVE-2017-1000405
The Linux Kernel versions 2.6.38 through 4.14 have a problematic use of pmd_mkdirty() in the touch_pmd() function inside the THP implementation. touch_pmd() can be reached by get_user_pages(). In such case, the pmd will become dirty. This scenario breaks the new can_follow_write_pmd()'s logic - pmd can become dirty without going through a COW cycle. This bug is not as severe as the original "Dirty cow" because an ext4 file (or any other regular file) cannot be mapped using THP. Nevertheless, it does allow us to overwrite read-only huge pages. • https://www.exploit-db.com/exploits/44305 https://www.exploit-db.com/exploits/43199 https://github.com/bindecy/HugeDirtyCowPOC http://www.securityfocus.com/bid/102032 http://www.securitytracker.com/id/1040020 https://access.redhat.com/errata/RHSA-2018:0180 https://medium.com/bindecy/huge-dirty-cow-cve-2017-1000405-110eca132de0 https://source.android.com/security/bulletin/pixel/2018-02-01 https://access.redhat.com/security/cve/CVE-2017-1000405 https://bugzilla.redhat.com/show_bu • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
