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 flaws were found in the way the Linux kernel's file system implementation handled rename operations in which the source was inside and the destination was outside of a bind mount. A privileged user inside a container could use this flaw to escape the bind mount and, potentially, escalate their privileges on the system.

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 Xen ...

The join_session_keyring function in security/keys/process_keys.c in the Linux kernel mishandles object references in a certain error case, which allows local users to gain privileges or cause a denial of service (integer overflow and use-after-free) via crafted keyctl commands.
