CVSS: 7.6EPSS: 0%CPEs: 13EXPL: 1CVE-2017-10661 – Linux kernel < 4.10.15 - Race Condition Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-10661
Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing. Una condición de carrera en fs/timerfd.c en el kernel Linux en versiones anteriores a la 4.10.15 permite que usuarios locales obtengan privilegios o provoquen una denegación de servicio (corrupción de lista o use-after-free) mediante operaciones simultáneas de descriptor de archivo que aprovechan la cola inadecuada might_cancel. A race condition was found in the Linux kernel before version 4.11-rc1 in 'fs/timerfd.c' file which allows a local user to cause a kernel list corruption or use-after-free via simultaneous operations with a file descriptor which leverage improper 'might_cancel' queuing. An unprivileged local user could use this flaw to cause a denial of service of the system. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • https://www.exploit-db.com/exploits/43345 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1e38da300e1e395a15048b0af1e5305bd91402f6 http://www.debian.org/security/2017/dsa-3981 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.10.15 http://www.securityfocus.com/bid/100215 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://access.redhat.com/errata/RHSA-2019:4057 https://access.redhat.com/e • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

The sanity_check_raw_super function in fs/f2fs/super.c in the Linux kernel before 4.11.1 does not validate the segment count, which allows local users to gain privileges via unspecified vectors. La función sanity_check_raw_super en fs/f2fs/super.c en el kernel Linux en versiones anteriores a la 4.11.1 no valida el conteo de segmentos, 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=b9dd46188edc2f0d1f37328637860bb65a771124 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.11.1 http://www.securityfocus.com/bid/100215 https://bugzilla.redhat.com/show_bug.cgi?id=1481146 https://github.com/torvalds/linux/commit/b9dd46188edc2f0d1f37328637860bb65a771124 https://source.android.com/security/bulletin/2017-08-01 •
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.
