The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * A race condition flaw was found in the way the Linux kernel"s KVM subsystem handled PIT emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. * A NULL pointer dereference flaw was found in the way the Linux kernel"s Stream Control Transmission Proto ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A race condition flaw was found in the way the Linux kernel"s KVM subsystem handled PIT emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. * A memory corruption flaw was found in the way the USB ConnectTech WhiteHEAT serial driver processed completion commands s ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this proce ...

* A flaw was found in the way the Linux kernel"s SCTP implementation handled malformed or duplicate Address Configuration Change Chunks . A remote attacker could use either of these flaws to crash the system. * A flaw was found in the way the Linux kernel"s SCTP implementation handled the association"s output queue. A remote attacker could send specially crafted packets that would cause the syste ...

* A flaw was found in the way the Linux kernel handled GS segment register base switching when recovering from a #SS fault on an erroneous return to user space. A local, unprivileged user could use this flaw to escalate their privileges on the system. * A flaw was found in the way the Linux kernel"s SCTP implementation handled malformed or duplicate Address Configuration Change Chunks . A remote ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid system call, among others, also sets the saved set-user ...

KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for the standard Red Hat Enterprise Linux kernel. It was found that KVM"s Write to Model Specific Register instruction emulation would write non-canonical values passed in by the guest to certain MSRs in the host"s context. A privileged guest user could use this flaw to crash the hos ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * An integer overflow flaw was found in the way the Linux kernel"s Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file could possibly use this flaw to escalate their privileges on the system. * It was found that the X ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way Linux kernel"s Transparent Huge Pages implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. * A buffer overflow flaw was found in the way the Linux kernel"s eCryptfs implementation deco ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel"s XFS file system handled replacing of remote attributes under certain conditions. A local user with access to XFS file system mount could potentially use this flaw to escalate their privileges on the system. * It was found that the Linux kernel"s KVM implementation ...
