CVE-2018-10902 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2026-07-07 4.6 MEDIUM 7.8 HIGH
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.
CVE-2025-6021 2 Redhat, Xmlsoft 20 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 17 more 2026-06-30 N/A 7.5 HIGH
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
CVE-2025-2784 2 Gnome, Redhat 21 Libsoup, Codeready Linux Builder, Codeready Linux Builder For Arm64 and 18 more 2026-06-30 N/A 7.0 HIGH
A flaw was found in libsoup. The package is vulnerable to a heap buffer over-read when sniffing content via the skip_insight_whitespace() function. Libsoup clients may read one byte out-of-bounds in response to a crafted HTTP response by an HTTP server.
CVE-2023-5367 4 Debian, Fedoraproject, Redhat and 1 more 12 Debian Linux, Fedora, Enterprise Linux and 9 more 2026-06-23 N/A 7.8 HIGH
A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service.
CVE-2024-1086 5 Debian, Fedoraproject, Linux and 2 more 15 Debian Linux, Fedora, Linux Kernel and 12 more 2026-06-17 N/A 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. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.
CVE-2024-0409 4 Fedoraproject, Redhat, Tigervnc and 1 more 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more 2026-06-17 N/A 7.8 HIGH
A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context.
CVE-2024-0408 4 Fedoraproject, Redhat, Tigervnc and 1 more 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more 2026-06-17 N/A 5.5 MEDIUM
A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.
CVE-2023-6816 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux Desktop and 4 more 2026-06-17 N/A 9.8 CRITICAL
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.
CVE-2023-5869 2 Postgresql, Redhat 21 Postgresql, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 18 more 2026-06-17 N/A 8.8 HIGH
A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory.
CVE-2023-5455 3 Fedoraproject, Freeipa, Redhat 21 Fedora, Freeipa, Codeready Linux Builder and 18 more 2026-06-17 N/A 6.5 MEDIUM
A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing already logged-in user. An attacker would always have to go through a new authentication attempt.
CVE-2023-46847 2 Redhat, Squid-cache 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 7 more 2026-06-17 N/A 8.6 HIGH
Squid is vulnerable to a Denial of Service, where a remote attacker can perform buffer overflow attack by writing up to 2 MB of arbitrary data to heap memory when Squid is configured to accept HTTP Digest Authentication.
CVE-2023-3972 1 Redhat 19 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Desktop and 16 more 2026-06-17 N/A 7.8 HIGH
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).
CVE-2023-3899 2 Fedoraproject, Redhat 20 Fedora, Enterprise Linux, Enterprise Linux Desktop and 17 more 2026-06-17 N/A 7.8 HIGH
A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root.
CVE-2023-0494 3 Fedoraproject, Redhat, X.org 18 Fedora, Enterprise Linux, Enterprise Linux Aus and 15 more 2026-06-17 N/A 7.8 HIGH
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions.
CVE-2023-0179 4 Canonical, Fedoraproject, Linux and 1 more 14 Ubuntu Linux, Fedora, Linux Kernel and 11 more 2026-06-17 N/A 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-2022-4254 2 Fedoraproject, Redhat 13 Sssd, Enterprise Linux, Enterprise Linux Desktop and 10 more 2026-06-17 N/A 8.8 HIGH
sssd: libsss_certmap fails to sanitise certificate data used in LDAP filters
