https://notcve.org/view.php?id=CVE-2019-9162
25 Feb 2019 — In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper. En el kernel de Linux, en versiones anteriores a la 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c en el módulo SNMP NAT tiene comprobaciones de longitud ASN.1 insuficientes (conocido como... • https://www.exploit-db.com/exploits/46477 • CWE-787: Out-of-bounds Write •

22 Feb 2019 — In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other impact by inducing a high load. En el kernel de Linux, en versiones anteriores a la 4.20.2, kernel/sched/fair.c gestiona leaf cfs_rq de manera incorrecta, lo que permite que los atacantes provoquen una denegación de servicio (bucle infinito en update_blocked_averages) o, posiblemente, otro impacto si... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c40f7d74c741a907cfaeb73a7697081881c497d0 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

22 Feb 2019 — In the Linux kernel before 4.20.5, attackers can trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a "service ipmievd restart" loop. En el kernel de Linux, en versiones anteriores a la 4.20.5, los atacantes pueden desencadenar un uso de memoria previamente liberada y un estado "OOPS" en drivers/char/ipmi/ipmi_msghandler.c haciendo que cierto código se ejecute de forma simultánea, tal y como queda demostrado c... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=77f8269606bf95fcb232ee86f6da80886f1dfae8 • CWE-416: Use After Free •

16 Feb 2019 — The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. La implementación KVM en el kernel de Linux, hasta la versión 4.20.5, tiene un uso de memoria previamente liberada. A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested (=1) virtualization is enabled. This high resolution timer(hrtimer) runs when a L2 guest is active.
