CVE-2020-15707 [MEDIUM] CWE-362 CVE-2020-15707: Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efili Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command

CVE-2025-7519 [MEDIUM] CWE-787 CVE-2025-7519: A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy f

CVE-2026-9149 [MEDIUM] CWE-122 CVE-2026-9149: A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).

CVE-2020-1726 [MEDIUM] CWE-552 CVE-2020-1726: A flaw was discovered in Podman where it incorrectly allows containers when created to overwrite exi A flaw was discovered in Podman where it incorrectly allows containers when created to overwrite existing files in volumes, even if they are mounted as read-only. When a user runs a malicious container or a container based on a malicious image with an attached volume that is used for the first time, it is possible to trigger the flaw and overwrite fil

CVE-2026-12725 [MEDIUM] CWE-122 CVE-2026-12725: A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both enabled, logging of DS or DNSKEY replies containing unsupported algorithm or digest types can cause dnsmasq to write past the end of an internal logging buffer. A remote attacker able to supply such a DNS response may crash the dnsmasq process, resul

CVE-2019-1002101 [MEDIUM] CWE-59 CVE-2019-1002101: The kubectl cp command allows copying files between containers and the user machine. To copy files f The kubectl cp command allows copying files between containers and the user machine. To copy files from a container, Kubernetes creates a tar inside the container, copies it over the network, and kubectl unpacks it on the user’s machine. If the tar binary in the container is malicious, it could run any code and output unexpected, malicious result

CVE-2023-27561 [HIGH] CVE-2023-27561: runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to libc runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. NOTE: this issue exists because of a CVE-2019-19921 regression.

CVE-2021-3609 [HIGH] CWE-362 CVE-2021-3609: .A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can .A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.

CVE-2020-1708 [HIGH] CWE-266 CVE-2020-1708: It has been found in openshift-enterprise version 3.11 and all openshift-enterprise versions from 4. It has been found in openshift-enterprise version 3.11 and all openshift-enterprise versions from 4.1 to, including 4.3, that multiple containers modify the permissions of /etc/passwd to make them modifiable by users other than root. An attacker with access to the running container can exploit this to modify /etc/passwd to add a user and escalate their

CVE-2020-10749 [MEDIUM] CWE-300 CVE-2020-10749: A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other containers, to redirect traffic to the maliciou

CVE-2025-5351 [MEDIUM] CWE-415 CVE-2025-5351: A flaw was found in the key export functionality of libssh. The issue occurs in the internal functio A flaw was found in the key export functionality of libssh. The issue occurs in the internal function responsible for converting cryptographic keys into serialized formats. During error handling, a memory structure is freed but not cleared, leading to a potential double free issue if an additional failure occurs later in the function. This condition m

CVE-2024-50311 [MEDIUM] CWE-770 CVE-2024-50311: A denial of service (DoS) vulnerability was found in OpenShift. This flaw allows attackers to exploi A denial of service (DoS) vulnerability was found in OpenShift. This flaw allows attackers to exploit the GraphQL batching functionality. The vulnerability arises when multiple queries can be sent within a single request, enabling an attacker to submit a request containing thousands of aliases in one query. This issue causes excessive resource consu

CVE-2021-3631 [MEDIUM] CWE-732 CVE-2021-3631: A flaw was found in libvirt while it generates SELinux MCS category pairs for VMs' dynamic labels. T A flaw was found in libvirt while it generates SELinux MCS category pairs for VMs' dynamic labels.
