CVE-2025-22871 1 Redhat 13 Acm, Ansible Automation Platform, Cryostat and 10 more 2026-04-15 9.1 Critical
The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.
CVE-2024-21886 2 Redhat, Xorg 8 Enterprise Linux, Rhel Aus, Rhel E4s and 5 more 2026-04-15 7.8 High
A heap buffer overflow flaw was found in the DisableDevice function in the X.Org server. This issue may lead to an application crash or, in some circumstances, remote code execution in SSH X11 forwarding environments.
CVE-2025-14905 1 Redhat 12 Directory Server, Directory Server E4s, Directory Server Eus and 9 more 2026-04-15 7.2 High
A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).
CVE-2024-24582 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 7.5 High
Improper input validation in XmlCli feature for UEFI firmware for some Intel(R) processors may allow privileged user to potentially enable escalation of privilege via local access.
CVE-2024-5535 2 Openssl, Redhat 7 Openssl, Enterprise Linux, Jboss Core Services and 4 more 2026-04-15 9.1 Critical
Issue summary: Calling the OpenSSL API function SSL_select_next_proto with an empty supported client protocols buffer may cause a crash or memory contents to be sent to the peer. Impact summary: A buffer overread can have a range of potential consequences such as unexpected application beahviour or a crash. In particular this issue could result in up to 255 bytes of arbitrary private data from memory being sent to the peer leading to a loss of confidentiality. However, only applications that directly call the SSL_select_next_proto function with a 0 length list of supported client protocols are affected by this issue. This would normally never be a valid scenario and is typically not under attacker control but may occur by accident in the case of a configuration or programming error in the calling application. The OpenSSL API function SSL_select_next_proto is typically used by TLS applications that support ALPN (Application Layer Protocol Negotiation) or NPN (Next Protocol Negotiation). NPN is older, was never standardised and is deprecated in favour of ALPN. We believe that ALPN is significantly more widely deployed than NPN. The SSL_select_next_proto function accepts a list of protocols from the server and a list of protocols from the client and returns the first protocol that appears in the server list that also appears in the client list. In the case of no overlap between the two lists it returns the first item in the client list. In either case it will signal whether an overlap between the two lists was found. In the case where SSL_select_next_proto is called with a zero length client list it fails to notice this condition and returns the memory immediately following the client list pointer (and reports that there was no overlap in the lists). This function is typically called from a server side application callback for ALPN or a client side application callback for NPN. In the case of ALPN the list of protocols supplied by the client is guaranteed by libssl to never be zero in length. The list of server protocols comes from the application and should never normally be expected to be of zero length. In this case if the SSL_select_next_proto function has been called as expected (with the list supplied by the client passed in the client/client_len parameters), then the application will not be vulnerable to this issue. If the application has accidentally been configured with a zero length server list, and has accidentally passed that zero length server list in the client/client_len parameters, and has additionally failed to correctly handle a "no overlap" response (which would normally result in a handshake failure in ALPN) then it will be vulnerable to this problem. In the case of NPN, the protocol permits the client to opportunistically select a protocol when there is no overlap. OpenSSL returns the first client protocol in the no overlap case in support of this. The list of client protocols comes from the application and should never normally be expected to be of zero length. However if the SSL_select_next_proto function is accidentally called with a client_len of 0 then an invalid memory pointer will be returned instead. If the application uses this output as the opportunistic protocol then the loss of confidentiality will occur. This issue has been assessed as Low severity because applications are most likely to be vulnerable if they are using NPN instead of ALPN - but NPN is not widely used. It also requires an application configuration or programming error. Finally, this issue would not typically be under attacker control making active exploitation unlikely. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. Due to the low severity of this issue we are not issuing new releases of OpenSSL at this time. The fix will be included in the next releases when they become available.
CVE-2025-7493 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 9.1 Critical
A privilege escalation flaw from host to domain administrator was found in FreeIPA. This vulnerability is similar to CVE-2025-4404, where it fails to validate the uniqueness of the krbCanonicalName. While the previously released version added validations for the admin@REALM credential, FreeIPA still does not validate the root@REALM canonical name, which can also be used as the realm administrator's name. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration.
CVE-2025-49176 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-04-15 7.3 High
A flaw was found in the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check.
CVE-2025-46421 1 Redhat 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more 2026-04-15 6.8 Medium
A flaw was found in libsoup. When libsoup clients encounter an HTTP redirect, they mistakenly send the HTTP Authorization header to the new host that the redirection points to. This allows the new host to impersonate the user to the original host that issued the redirect.
CVE-2025-0624 1 Redhat 7 Enterprise Linux, Openshift, Rhel Aus and 4 more 2026-04-15 7.6 High
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.
CVE-2024-45770 1 Redhat 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more 2026-04-15 4.4 Medium
A vulnerability was found in Performance Co-Pilot (PCP). This flaw can only be exploited if an attacker has access to a compromised PCP system account. The issue is related to the pmpost tool, which is used to log messages in the system. Under certain conditions, it runs with high-level privileges.
CVE-2024-29214 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 7.5 High
Improper input validation in UEFI firmware CseVariableStorageSmm for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.
CVE-2025-20623 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 5.6 Medium

CVE-2025-14523 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-04-15 8.2 High
A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.
CVE-2023-43758 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 8.2 High
Improper input validation in UEFI firmware for some Intel(R) processors may allow a privileged user to potentially enable escalation of privilege via local access.
CVE-2023-31356 1 Redhat 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more 2026-04-15 4.4 Medium
Incomplete system memory cleanup in SEV firmware could allow a privileged attacker to corrupt guest private memory, potentially resulting in a loss of data integrity.
CVE-2023-4727 1 Redhat 6 Certificate System Eus, Enterprise Linux, Rhel Aus and 3 more 2026-04-15 7.5 High
