CVE-2020-36558 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Rhel Eus and 2 more 2026-10-08 5.1 Medium
A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer dereference and general protection fault.
CVE-2021-34866 3 Linux, Netapp, Redhat 19 Linux Kernel, H300e, H300e Firmware and 16 more 2026-10-08 7.8 High
This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-14689.
CVE-2020-27827 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more 28 Fedora, Lldpd, Openvswitch and 25 more 2025-12-03 7.5 High
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2021-3156 9 Beyondtrust, Debian, Fedoraproject and 6 more 38 Privilege Management For Mac, Privilege Management For Unix\/linux, Debian Linux and 35 more 2025-11-10 7.8 High
Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character.
CVE-2021-3560 4 Canonical, Debian, Polkit Project and 1 more 10 Ubuntu Linux, Debian Linux, Polkit and 7 more 2025-11-06 7.8 High
It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25686 5 Arista, Debian, Fedoraproject and 2 more 10 Eos, Debian Linux, Fedora and 7 more 2025-11-04 3.7 Low
A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name. This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned in the "Birthday Attacks" section of RFC5452. If chained with CVE-2020-25684, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-25685 5 Arista, Debian, Fedoraproject and 2 more 10 Eos, Debian Linux, Fedora and 7 more 2025-11-04 3.7 Low
A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is) this flaw allows an off-path attacker to find several different domains all having the same hash, substantially reducing the number of attempts they would have to perform to forge a reply and get it accepted by dnsmasq. This is in contrast with RFC5452, which specifies that the query name is one of the attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-25684 5 Arista, Debian, Fedoraproject and 2 more 10 Eos, Debian Linux, Fedora and 7 more 2025-11-04 3.7 Low
A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in the forward.c:reply_query() if the reply destination address/port is used by the pending forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query, substantially reducing the number of attempts an attacker on the network would have to perform to forge a reply and get it accepted by dnsmasq. This issue contrasts with RFC5452, which specifies a query's attributes that all must be used to match a reply. This flaw allows an attacker to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25685 or CVE-2020-25686, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2021-3621 2 Fedoraproject, Redhat 10 Fedora, Sssd, Enterprise Linux and 7 more 2025-11-03 8.8 High
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

CVE-2021-3677 3 Fedoraproject, Postgresql, Redhat 9 Fedora, Postgresql, Enterprise Linux and 6 more 2024-11-21 6.5 Medium
A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.

A privileged local user could use this flaw to crash the system or escalate their privileges on the system.
CVE-2021-3609 3 Linux, Netapp, Redhat 46 Linux Kernel, H300e, H300e Firmware and 43 more 2024-11-21 7.0 High
.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.
