Privilege Escalation
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 THP implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent...
Denial Of Service (DoS)
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.
