CVE-2018-3639 NOMISEC MEDIUM WORKING POC
Intel Atom C/E/X5/X7/Z - Information Disclosure via Speculative Store Bypass
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

CVE-2016-1583 WRITEUP HIGH WRITEUP
Linux kernel <4.6.3 - Privilege Escalation
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.
CVSS 7.8
CVE-2019-11477 WRITEUP HIGH WRITEUP
Linux Kernel 2.6.29-3.16.69 - Denial of Service via TCP SACK Integer Overflow
Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff.

CVE-2015-1331 WRITEUP WRITEUP
LXC < 1.1.2 - Arbitrary File Creation via Symlink Attack on /run/lock/lxc/*
lxclock.c in LXC 1.1.2 and earlier allows local users to create arbitrary files via a symlink attack on /run/lock/lxc/*.
CVE-2019-11479 WRITEUP HIGH WRITEUP
Linux Kernel 4.4-4.4.182 - Denial of Service via TCP MSS Fragmentation
Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363.

CVE-2019-5599 WRITEUP HIGH WRITEUP
FreeBSD 12.0-STABLE before r349197 and 12.0-RELEASE before 12.0-RELEASE-p6 - Denial of Service via RACK TCP Stack
In FreeBSD 12.0-STABLE before r349197 and 12.0-RELEASE before 12.0-RELEASE-p6, a bug in the non-default RACK TCP stack can allow an attacker to cause several linked lists to grow unbounded and cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service.
