CVE-2016-4565 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2026-06-17 7.2 HIGH 7.8 HIGH
The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3 incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface.
CVE-2016-4558 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2026-06-17 6.9 MEDIUM 7.0 HIGH
The BPF subsystem in the Linux kernel before 4.5.5 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted application on (1) a system with more than 32 Gb of memory, related to the program reference count or (2) a 1 Tb system, related to the map reference count.
CVE-2016-4556 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2026-06-17 5.0 MEDIUM 7.5 HIGH
Double free vulnerability in Esi.cc in Squid 3.x before 3.5.18 and 4.x before 4.0.10 allows remote servers to cause a denial of service (crash) via a crafted Edge Side Includes (ESI) response.
