A flaw was found in the Linux kernel’s implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14314 5 Canonical, Debian, Linux and 2 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2024-11-21 5.5 Medium
A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability.
CVE-2020-14305 3 Linux, Netapp, Redhat 12 Linux Kernel, A250, A250 Firmware and 9 more 2024-11-21 8.1 High
An out-of-bounds memory write flaw was found in how the Linux kernel’s Voice Over IP H.323 connection tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote user to crash the system, causing a denial of service. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-13974 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 7.8 High
An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case.
CVE-2020-12888 7 Canonical, Debian, Fedoraproject and 4 more 45 Ubuntu Linux, Debian Linux, Fedora and 42 more 2024-11-21 5.3 Medium
The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.
CVE-2020-12826 3 Canonical, Linux, Redhat 5 Ubuntu Linux, Linux Kernel, Enterprise Linux and 2 more 2024-11-21 5.3 Medium
A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.
