CVE-2016-10044 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that a buffer overflow existed in the Bluetooth stack of
the Linux kernel when handling L2CAP configuration responses. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2017-1000251)
It was discovered that the asynchronous I/O (aio) subsystem of the Linux
kernel did not properly set permissions on aio memory mappings in some
situations. An attacker could use this to more easily exploit other
vulnerabilities. (CVE-2016-10044)

CVE-2017-6214 [HIGH] CWE-835 kernel: ipv4/tcp: Infinite loop in tcp_splice_read()
kernel: ipv4/tcp: Infinite loop in tcp_splice_read()
The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag.
A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality could allow a remote attacker to force the kernel to enter a condition in which it could loop indefinitely.
Statement: This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 as the code with the flaw is not present in the products listed.
