script_tag(name:"insight", value:"A flaw was discovered in the Linux kernel's USB subsystem in the __usb_get_extra_descriptor() function in the drivers/usb/core/usb.c which mishandles a size check during the reading of an extra descriptor data. By using a specially crafted USB device which sends a forged extra descriptor, an unprivileged user with physical access to the system can potentially cause a privilege escalation or trigger a system crash or lock up and thus to cause a denial of service (DoS).(CVE-2018-20169)
Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused.(CVE-2018-18281)
A division-by-zero in set_termios(), when debugging is enabled, was found in the Linux kernel. When the [io_ti] driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the change_port_settings() in the drivers/usb/serial/io_ti.c so that the divisor value becomes zero and causes a system crash resulting in a denial of service. (CVE-2017-18360)
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.(CVE-2018-10881)
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write and a denial of service or unspecified other impact is possible by mounting and operating a crafted ext4 filesystem image.(CVE-2018-10878)");
