Red Hat Security Advisory 2019-3517-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include denial of service, heap overflow, information leakage, and use-after-free vulnerabilities.
6d1ca3b131a0815a02a22b4f2f5f2856Red Hat Security Advisory 2015-1221-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A NULL pointer dereference flaw was found in the way the Linux kernel's virtual console implementation handled reference counting when accessing pseudo-terminal device files. A local, unprivileged attacker could use this flaw to crash the system. It was found that the Linux kernel's ping socket implementation did not properly handle socket unhashing during spurious disconnects, which could lead to a use-after-free flaw. On x86-64 architecture systems, a local user able to create ping sockets could use this flaw to crash the system. On non-x86-64 architecture systems, a local user able to create ping sockets could use this flaw to escalate their privileges on the system.
7569846c179aefca0adca037b66b1cefRed Hat Security Advisory 2015-1139-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.

fc00346bd52f716a2404d8babb47d690Ubuntu Security Notice 2565-1 - An integer overflow was discovered in the stack randomization feature of the Linux kernel on 64 bit platforms. A local attacker could exploit this flaw to bypass the Address Space Layout Randomization (ASLR) protection mechanism. An information leak was discovered in the Linux Kernel's handling of userspace configuration of the link layer control (LLC). A local user could exploit this flaw to read data from other sysctl settings. Various other issues were also addressed.

f2a8263419638b026a18d407958093f0Ubuntu Security Notice 2563-1 - Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP (Stream Control Transmission Protocol) subsystem during INIT collisions. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges on the system. Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets to too many different dsts/too fast. A remote attacker can exploit this flaw to cause a denial of service (system crash). Various other issues were also addressed.
40173d94425fb5b108eb49691e01129bUbuntu Security Notice 2560-1 - An integer overflow was discovered in the stack randomization feature of the Linux kernel on 64 bit platforms. A local attacker could exploit this flaw to bypass the Address Space Layout Randomization (ASLR) mitigation mechanism. An information leak was discovered in the Linux kernel's handling of userspace configuration of the link layer control (LLC). A local user could exploit this flaw to read data from other sysctl settings. Various other issues were also addressed.

9de01098df2072bf002760336bd4a21bUbuntu Security Notice 2561-1 - It was discovered that the Linux kernel's Infiniband subsystem did not properly sanitize its input parameters while registering memory regions from userspace. A local user could exploit this flaw to cause a denial of service (system crash) or to potentially gain administrative privileges. An integer overflow was discovered in the stack randomization feature of the Linux kernel on 64 bit platforms. A local attacker could exploit this flaw to bypass the Address Space Layout Randomization (ASLR) mitigation mechanism. Various other issues were also addressed.
70b1d505b025a959771b90b67b78d076Debian Linux Security Advisory 3170-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leaks or privilege escalation.
027f0aa2e94634ffb4a7876370d57d9dA bug in Linux ASLR implementation for versions prior to 3.19-rc3 has been found. The issue is that the stack for processes is not properly randomized on some 64 bit architectures due to an integer overflow.
