The sanity_check_ckpt function in fs/f2fs/super.c in the Linux kernel before 4.12.4 does not validate the blkoff and segno arrays, which allows local users to gain privileges via unspecified vectors. La función sanity_check_ckpt en fs/f2fs/super.c en el kernel Linux en versiones anteriores a la 4.12.4 no valida los arrays blkoff y segno, lo que permite que usuarios locales obtengan privilegios mediante vectores sin especificar. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=15d3042a937c13f5d9244241c7a9c8416ff6e82a http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.12.4 http://www.securityfocus.com/bid/100215 https://bugzilla.redhat.com/show_bug.cgi?id=1481149 https://github.com/torvalds/linux/commit/15d3042a937c13f5d9244241c7a9c8416ff6e82a https://source.android.com/security/bulletin/2017-08-01 • CWE-129: Improper Validation of Array Index •
CVSS: 7.0EPSS: 0%CPEs: 6EXPL: 4CVE-2017-1000112 – Linux Kernel - UDP Fragmentation Offset 'UFO' Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-1000112
Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, copy = maxfraglen - skb->len becomes negative on the non-UFO path and the branch to allocate new skb is taken. This triggers fragmentation and computation of fraggap = skb_prev->len - maxfraglen. • https://www.exploit-db.com/exploits/45147 https://www.exploit-db.com/exploits/47169 https://www.exploit-db.com/exploits/43418 https://github.com/ol0273st-s/CVE-2017-1000112-Adpated http://seclists.org/oss-sec/2017/q3/277 http://www.debian.org/security/2017/dsa-3981 http://www.securityfocus.com/bid/100262 http://www.securitytracker.com/id/1039162 https://access.redhat.com/errata/RHSA-2017:2918 https://access.redhat.com/errata/RHSA-2017:2930 https://access.redh • CWE-122: Heap-based Buffer Overflow CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION.

CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 1CVE-2017-7533 – Linux Kernel < 3.16.39 (Debian 8 x64) - 'inotfiy' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-7533
Race condition in the fsnotify implementation in the Linux kernel through 4.12.4 allows local users to gain privileges or cause a denial of service (memory corruption) via a crafted application that leverages simultaneous execution of the inotify_handle_event and vfs_rename functions. Una condición de carrera en la implementación de fsnotify en el kernel de Linux hasta la versión 4.12.4, permite a los usuarios locales alcanzar privilegios o causar una denegación de servicio (corrupción de memoria) por medio de una aplicación creada que aprovecha la ejecución simultánea de las funciones inotify_handle_event y vfs_rename. A race condition was found in the Linux kernel, present since v3.14-rc1 through v4.12. The race happens between threads of inotify_handle_event() and vfs_rename() while running the rename operation against the same file. As a result of the race the next slab data or the slab's free list pointer can be corrupted with attacker-controlled data, which may lead to the privilege escalation. • https://www.exploit-db.com/exploits/44302 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=49d31c2f389acfe83417083e1208422b4091cd9e http://openwall.com/lists/oss-security/2017/08/03/2 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.openwall.com/lists/oss-security/2019/06/27/7 http://www.openwall.com/lists/oss-security/2019/06/28/1 http://www.openwall.com/lists/oss-security/2019/06/28& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-642: External Control of Critical State Data •
