17 Apr 2020 — ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. ntpd en ntp versiones anteriores a 4.2.8p14 y versiones 4.3.x anteriores a 4.3.100, permite a un atacante fuera de ruta bloquear una sincronización no autenticada por medio de un paquete en modo server con una dirección IP de origen falsifica... • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00005.html • CWE-346: Origin Validation Error CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-8835
30 Mar 2020 — In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29.

17 Mar 2020 — The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 ("The Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors.") was discovered to be incomplete, meaning that in versions of the kernel before 4.15.0-91.92, an attacker could use this vulnerability to expose sensitive information.

https://notcve.org/view.php?id=CVE-2019-18282
16 Jan 2020 — The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

23 Dec 2019 — An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed.
