DATE CVE VULNERABILITY TITLE RISK
2019-03-21 CVE-2019-7222 The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak. 5.5
2019-03-21 CVE-2019-7221 Use After Free vulnerability in multiple products
The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free.
7.8
2019-03-05 CVE-2019-9213 NULL Pointer Dereference vulnerability in multiple products
In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms.

5.5
2019-02-25 CVE-2019-9162 Out-of-bounds Write vulnerability in multiple products
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.

4.6
2019-02-22 CVE-2019-9003 Use After Free vulnerability in multiple products
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.

7.8
2019-02-22 CVE-2018-20784 Infinite Loop vulnerability in multiple products
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.

linux canonical redhat CWE-835
7.5
2019-02-21 CVE-2019-8980 Memory Leak vulnerability in multiple products
A memory leak in the kernel_read_file function in fs/exec.c in the Linux kernel through 4.20.11 allows attackers to cause a denial of service (memory consumption) by triggering vfs_read failures.

linux canonical opensuse debian CWE-401
7.5
2019-02-18 CVE-2019-8912 Use After Free vulnerability in multiple products
In the Linux kernel through 4.20.11, af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr.

7.2
2019-02-15 CVE-2019-6974 Use After Free vulnerability in multiple products
In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free.
