https://notcve.org/view.php?id=CVE-2019-3016
31 Jan 2020 — In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. This problem is limit to the host running linux kernel 4.10 with a guest running linux kernel 4.16 or later. The problem mainly affects AMD processors but Intel CPUs cannot be ruled out. En un Linux KVM invitado que posee PV TLB habilitado, un proceso en el kernel invitado puede ser capaz de leer ubicaciones de memoria de otro proceso en el mismo invitado. ... • http://packetstormsecurity.com/files/157233/Kernel-Live-Patch-Security-Notice-LSN-0065-1.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

27 Jan 2020 — In the Linux kernel before 5.3.4, fib6_rule_lookup in net/ipv6/ip6_fib.c mishandles the RT6_LOOKUP_F_DST_NOREF flag in a reference-count decision, leading to (for example) a crash that was identified by syzkaller, aka CID-7b09c2d052db. En el kernel de Linux versiones anteriores a 5.3.4, la función fib6_rule_lookup en el archivo net/ipv6/ip6_fib.c maneja inapropiadamente el flag RT6_LOOKUP_F_DST_NOREF en una decisión de conteo de referencias, lo que conlleva a (por ejemplo) un bloqueo que fue identificado po... • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.4 • CWE-755: Improper Handling of Exceptional Conditions •

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.

15 Jan 2020 — The Linux kernel before 2.4.36-rc1 has a race condition. It was possible to bypass systrace policies by flooding the ptraced process with SIGCONT signals, which can can wake up a PTRACED process. El kernel de Linux versiones anteriores a 2.4.36-rc1, presenta una condición de carrera. Fue posible omitir las políticas systrace mediante la inundación del proceso ptraced con señales SIGCONT, lo que puede activar un proceso PTRACED. • http://taviso.decsystem.org/research.html • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction mechanism.
