DATE CVE VULNERABILITY TITLE RISK
2019-04-22 CVE-2019-3901 Improper Locking vulnerability in multiple products
A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.

linux debian netapp CWE-667
4.7
2019-04-12 CVE-2019-11191 Race Condition vulnerability in Linux Kernel
The Linux kernel through 5.0.7, when CONFIG_IA32_AOUT is enabled and ia32_aout is loaded, allows local users to bypass ASLR on setuid a.out programs (if any exist) because install_exec_creds() is called too late in load_aout_binary() in fs/binfmt_aout.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat.

linux CWE-362
2.5
2019-04-11 CVE-2019-3460 Improper Input Validation vulnerability in multiple products
A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found in the Linux kernel before 5.1-rc1.
6.5
2019-04-11 CVE-2019-3459 Out-of-bounds Read vulnerability in multiple products
A heap address information leak while using L2CAP_GET_CONF_OPT was discovered in the Linux kernel before 5.1-rc1.
6.5
2019-04-09 CVE-2019-3887 Incorrect Authorization vulnerability in multiple products
A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled.

5.6
2019-04-01 CVE-2019-8956 Use After Free vulnerability in multiple products
In the Linux Kernel before versions 4.20.8 and 4.19.21 a use-after-free error in the "sctp_sendmsg()" function (net/sctp/socket.c) when handling SCTP_SENDALL flag can be exploited to corrupt memory.

low complexity
linux canonical CWE-416
7.8
2019-03-21 CVE-2019-9857 Memory Leak vulnerability in Linux Kernel
In the Linux kernel through 5.0.2, the function inotify_update_existing_watch() in fs/notify/inotify/inotify_user.c neglects to call fsnotify_put_mark() with IN_MASK_CREATE after fsnotify_find_mark(), which will cause a memory leak (aka refcount leak).
local
low complexity
linux CWE-401
5.5
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.

low complexity
linux debian redhat opensuse canonical CWE-476
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.

linux netapp canonical CWE-787
4.6
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.
