| It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted. | ||||
| CVE-2021-3493 | 1 Canonical | 1 Ubuntu Linux | 2025-02-19 | 8.8 High |
| The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges. | ||||
| CVE-2010-3904 | 6 Canonical, Linux, Opensuse and 3 more | 8 Ubuntu Linux, Linux Kernel, Opensuse and 5 more | 2025-02-19 | 7.8 High |
| The rds_page_copy_user function in net/rds/page.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel before 2.6.36 does not properly validate addresses obtained from user space, which allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls. | ||||
| CVE-2023-0179 | 4 Canonical, Fedoraproject, Linux and 1 more | 15 Ubuntu Linux, Fedora, Linux Kernel and 12 more | 2025-02-19 | 7.8 High |
| A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. | ||||
| CVE-2019-11043 | 6 Canonical, Debian, Fedoraproject and 3 more | 26 Ubuntu Linux, Debian Linux, Fedora and 23 more | 2025-02-14 | 8.7 High |
| In PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24 and 7.3.x below 7.3.11 in certain configurations of FPM setup it is possible to cause FPM module to write past allocated buffers into the space reserved for FCGI protocol data, thus opening the possibility of remote code execution. | ||||
| CVE-2024-5493 | 3 Canonical, Fedoraproject, Google | 3 Ubuntu Linux, Fedora, Chrome | 2025-02-13 | 8.8 High |
| Heap buffer overflow in WebRTC in Google Chrome prior to 125.0.6422.141 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High) | ||||
| CVE-2023-3777 | 4 Canonical, Debian, Linux and 1 more | 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. | ||||
| CVE-2023-3389 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and 0e388fce7aec40992eadee654193cad345d62663 for 5.15 stable). | ||||

| CVE-2023-31248 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2025-02-13 | 7.8 High |
| Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()` failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace | ||||
| CVE-2023-2612 | 1 Canonical | 1 Ubuntu Linux | 2025-02-13 | 4.4 Medium |
| Jean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu Linux kernel contained a race condition when handling inode locking in some situations. A local attacker could use this to cause a denial of service (kernel deadlock). | ||||
| CVE-2023-1786 | 3 Canonical, Fedoraproject, Redhat | 4 Cloud-init, Ubuntu Linux, Fedora and 1 more | 2025-02-13 | 5.5 Medium |
| Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege. | ||||
| CVE-2022-2602 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2025-02-13 | 5.3 Medium |
| io_uring UAF, Unix SCM garbage collection | ||||
| CVE-2021-4034 | 7 Canonical, Oracle, Polkit Project and 4 more | 37 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 34 more | 2025-02-13 | 7.8 High |
| A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. | ||||
| CVE-2021-3560 | 4 Canonical, Debian, Polkit Project and 1 more | 10 Ubuntu Linux, Debian Linux, Polkit and 7 more | 2025-02-13 | 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-2018-19873 | 5 Canonical, Debian, Opensuse and 2 more | 6 Ubuntu Linux, Debian Linux, Backports and 3 more | 2025-02-11 | 9.8 Critical |
| An issue was discovered in Qt before 5.11.3. QBmpHandler has a buffer overflow via BMP data. | ||||
| CVE-2014-7169 | 17 Apple, Arista, Canonical and 14 more | 90 Mac Os X, Eos, Ubuntu Linux and 87 more | 2025-02-10 | 9.8 Critical |
| GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. | ||||
| CVE-2013-2423 | 4 Canonical, Opensuse, Oracle and 1 more | 5 Ubuntu Linux, Opensuse, Jre and 2 more | 2025-02-10 | 3.7 Low |
| Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK 7, allows remote attackers to affect integrity via unknown vectors related to HotSpot. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from the original researcher that this vulnerability allows remote attackers to bypass permission checks by the MethodHandles method and modify arbitrary public final fields using reflection and type confusion, as demonstrated using integer and double fields to disable the security manager. | ||||
| CVE-2013-0422 | 4 Canonical, Opensuse, Oracle and 1 more | 6 Ubuntu Linux, Opensuse, Jdk and 3 more | 2025-02-10 | 9.8 Critical |
| Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114. CVE-2013-0422 covers both the JMX/MBean and Reflection API issues. NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks. NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11. If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue. | ||||
| CVE-2011-3544 | 4 Canonical, Oracle, Redhat and 1 more | 9 Ubuntu Linux, Jdk, Jre and 6 more | 2025-02-10 | 9.8 Critical |
| Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE JDK and JRE 7 and 6 Update 27 and earlier allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability via unknown vectors related to Scripting. | ||||
