CVE-2023-6356 3 Debian, Linux, Redhat 17 Debian Linux, Linux Kernel, Codeready Linux Builder Eus and 14 more 2026-06-17 N/A 6.5 MEDIUM
A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service.
CVE-2023-5870 2 Postgresql, Redhat 16 Postgresql, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 13 more 2026-06-17 N/A 2.2 LOW
A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
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-2023-5633 2 Linux, Redhat 22 Linux Kernel, Codeready Linux Builder, Codeready Linux Builder Eus and 19 more 2026-06-17 N/A 7.8 HIGH
The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory objects were handled when they were being used to store a surface. When running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially use this flaw to escalate their privileges.
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-2023-5157 3 Fedoraproject, Mariadb, Redhat 12 Fedora, Mariadb, Enterprise Linux and 9 more 2026-06-17 N/A 7.5 HIGH
A vulnerability was found in MariaDB. An OpenVAS port scan on ports 3306 and 4567 allows a malicious remote client to cause a denial of service.
CVE-2023-4911 7 Canonical, Debian, Fedoraproject and 4 more 49 Ubuntu Linux, Debian Linux, Fedora and 46 more 2026-06-17 N/A 7.8 HIGH
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2023-4813 4 Fedoraproject, Gnu, Netapp and 1 more 21 Fedora, Glibc, Active Iq Unified Manager and 18 more 2026-06-17 N/A 5.9 MEDIUM
A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.
CVE-2023-46848 2 Redhat, Squid-cache 5 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 2 more 2026-06-17 N/A 8.6 HIGH
Squid is vulnerable to Denial of Service, where a remote attacker can perform DoS by sending ftp:// URLs in HTTP Request messages or constructing ftp:// URLs from FTP Native input.
CVE-2023-46846 2 Redhat, Squid-cache 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 5 more 2026-06-17 N/A 9.3 CRITICAL
SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote attacker to perform Request/Response smuggling past firewall and frontend security systems.
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-2023-3758 2 Fedoraproject, Redhat 23 Fedora, Sssd, Codeready Linux Builder and 20 more 2026-06-17 N/A 7.1 HIGH
A race condition flaw was found in sssd where the GPO policy is not consistently applied for authenticated users. This may lead to improper authorization issues, granting or denying access to resources inappropriately.
CVE-2023-2491 2 Gnu, Redhat 5 Emacs, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-06-17 N/A 7.8 HIGH
A flaw was found in the Emacs text editor. Processing a specially crafted org-mode code with the "org-babel-execute:latex" function in ob-latex.el can result in arbitrary command execution. This CVE exists because of a CVE-2023-28617 security regression for the emacs package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2.
CVE-2023-2295 2 Libreswan, Redhat 5 Libreswan, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-06-17 N/A 7.5 HIGH
A vulnerability was found in the libreswan library. This security issue occurs when an IKEv1 Aggressive Mode packet is received with only unacceptable crypto algorithms, and the response packet is not sent with a zero responder SPI. When a subsequent packet is received where the sender reuses the libreswan responder SPI as its own initiator SPI, the pluto daemon state machine crashes. No remote code execution is possible. This CVE exists because of a CVE-2023-30570 security regression for libreswan package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2.
CVE-2023-2203 2 Redhat, Webkitgtk 5 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 2 more 2026-06-17 N/A 8.8 HIGH
A flaw was found in the WebKitGTK package. An improper input validation issue may lead to a use-after-free vulnerability. This flaw allows attackers with network access to pass specially crafted web content files, causing a denial of service or arbitrary code execution. This CVE exists because of a CVE-2023-28205 security regression for the WebKitGTK package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2.
CVE-2023-1476 2 Linux, Redhat 6 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-06-17 N/A 7.0 HIGH
A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code. This issue occurs due to a race condition between rmap walk and mremap, allowing a local user to crash the system or potentially escalate their privileges on the system.
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-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
CVE-2022-2601 3 Fedoraproject, Gnu, Redhat 8 Fedora, Grub2, Enterprise Linux Eus and 5 more 2026-06-17 N/A 8.6 HIGH
A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism.
