CVE-2020-24587 7 Arista, Cisco, Debian and 4 more 333 C-100, C-100 Firmware, C-110 and 330 more 2024-11-21 2.6 Low
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.
CVE-2020-24586 6 Arista, Debian, Ieee and 3 more 45 C-200, C-200 Firmware, C-230 and 42 more 2024-11-21 3.5 Low
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
CVE-2020-24490 3 Bluez, Linux, Redhat 3 Bluez, Linux Kernel, Enterprise Linux 2024-11-21 6.5 Medium
Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of service via adjacent access. This affects all Linux kernel versions that support BlueZ.
CVE-2020-24394 6 Canonical, Linux, Opensuse and 3 more 11 Ubuntu Linux, Linux Kernel, Leap and 8 more 2024-11-21 7.1 High
In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.
CVE-2020-1749 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more 2024-11-21 7.5 High
A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
CVE-2020-16166 8 Canonical, Debian, Fedoraproject and 5 more 18 Ubuntu Linux, Debian Linux, Fedora and 15 more 2024-11-21 3.7 Low
The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.
CVE-2020-15780 4 Canonical, Linux, Opensuse and 1 more 6 Ubuntu Linux, Linux Kernel, Leap and 3 more 2024-11-21 6.7 Medium
An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30.
CVE-2020-15437 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-11-21 4.4 Medium
The Linux kernel before version 5.8 is vulnerable to a NULL pointer dereference in drivers/tty/serial/8250/8250_core.c:serial8250_isa_init_ports() that allows local users to cause a denial of service by using the p->serial_in pointer which uninitialized.
CVE-2020-15436 4 Broadcom, Linux, Netapp and 1 more 37 Brocade Fabric Operating System Firmware, Linux Kernel, A250 and 34 more 2024-11-21 6.7 Medium
Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field.
CVE-2020-14386 5 Debian, Fedoraproject, Linux and 2 more 7 Debian Linux, Fedora, Linux Kernel and 4 more 2024-11-21 6.7 Medium
A flaw was found in the Linux kernel before 5.9-rc4. Memory corruption can be exploited to gain root privileges from unprivileged processes. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2020-14385 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2024-11-21 5.5 Medium
A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-14356 6 Canonical, Debian, Linux and 3 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2024-11-21 7.8 High
A flaw null pointer dereference in the Linux kernel cgroupv2 subsystem in versions before 5.7.10 was found in the way when reboot the system. A local user could use this flaw to crash the system or escalate their privileges on the system.
CVE-2020-14351 3 Debian, Linux, Redhat 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more 2024-11-21 7.8 High
A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14331 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Extras Rt 2024-11-21 6.6 Medium
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.
