Jun 29, 2026A flaw was found in Yelp due to an overly permissive Content Security Policy (CSP) implementation provided by yelp-xsl.CVE-2026-13601 · Other software · Red Hat · reported by Red HatHigh 7.1
A flaw was found in Yelp due to an overly permissive Content Security Policy (CSP) implementation provided by yelp-xsl. A malicious Flatpak application can open crafted help content through the OpenURI portal.

Jul 23, 2025A Local Privilege Escalation (LPE) vulnerability has been discovered in pam-config within Linux Pluggable Authentication Modules (PAM).CVE-2025-6018 · Other software · Red Hat · reported by Red HatHigh 7.8
A Local Privilege Escalation (LPE) vulnerability has been discovered in pam-config within Linux Pluggable Authentication Modules (PAM). This flaw allows an unprivileged local attacker (for example, a user logged in via SSH) to obtain the elevated privileges normally reserved for a physically present, "allow_active" user. The highest risk is that the attacker can then perform all allow_active yes Polkit actions, which are typically restricted to console users, potentially gaining unauthorized control over system configurations, services, or other sensitive operations.

A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grub_strcpy() function. During this step, it fails to consider the environment variable length when allocating the internal buffer, resulting in an out-of-bounds write. If correctly exploited, this issue may result in remote code execution through the same network segment grub is searching for the boot information, which can be used to by-pass secure boot protections.

A log spoofing flaw was found in the Tuned package due to improper sanitization of some API arguments. This flaw allows an attacker to pass a controlled sequence of characters; newlines can be inserted into the log. Instead of the 'evil' the attacker could mimic a valid TuneD log line and trick the administrator. The quotes '' are usually used in TuneD logs citing raw user input, so there will always be the ' character ending the spoofed input, and the administrator can easily overlook this. This logged string is later used in logging and in the output of utilities, for example, `tuned-adm get_instances` or other third-party programs that use Tuned's D-Bus interface for such operations.

A flaw was found in the libreswan client plugin for NetworkManager (NetkworkManager-libreswan), where it fails to properly sanitize the VPN configuration from the local unprivileged user. In this configuration, composed by a key-value format, the plugin fails to escape special characters, leading the application to interpret values as keys. One of the most critical parameters that could be abused by a malicious user is the `leftupdown`key. This key takes an executable command as a value and is used to specify what executes as a callback in NetworkManager-libreswan to retrieve configuration settings back to NetworkManager. As NetworkManager uses Polkit to allow an unprivileged user to control the system's network configuration, a malicious actor could achieve local privilege escalation and potential code execution as root in the targeted machine by creating a malicious configuration.

A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum. It is also possible to force a derived key to be all zeros instead of an unpredictable value. This may have follow-on implications for the Go TLS stack.

A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client’s session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the user’s password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principal’s password).

Jan 18, 2024A flaw was found in the X.Org server.CVE-2024-0408 · Other software · Red Hat · reported by Red HatMedium 5.5
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.

Jan 10, 2024A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA.CVE-2023-5455 · Other software · Red Hat · reported by Red HatMedium 6.5
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.

Nov 1, 2023A vulnerability was found in insights-client.CVE-2023-3972 · Other software · Red Hat · reported by Red HatHigh 7.8
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).

A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed.

Sep 25, 2023An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel.CVE-2023-42753 · Other software · Red Hat · reported by Red HatHigh 7
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.

Aug 23, 2023A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization.CVE-2023-3899 · Other software · Red Hat · reported by Red HatHigh 7.8
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.

Jul 21, 2023A missing allocation check in sftp server processing read requests may cause a NULL dereference on low-memory conditions.CVE-2023-3603 · Other software · Red Hat · reported by Red HatLow 3.1
A missing allocation check in sftp server processing read requests may cause a NULL dereference on low-memory conditions. The malicious client can request up to 4GB SFTP reads, causing allocation of up to 4GB buffers, which was not being checked for failure. This will likely crash the authenticated user's sftp server connection (if implemented as forking as recommended). For thread-based servers, this might also cause DoS for legitimate users. Given this code is not in any released versions, no security releases have been issued.
