CVE-2026-3832 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-06-02 N/A 3.7 LOW
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
CVE-2026-3833 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-06-02 N/A 6.5 MEDIUM
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-33845 2 Gnu, Redhat 3 Gnutls, Enterprise Linux, Openshift Container Platform 2026-06-02 N/A 7.5 HIGH
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
CVE-2023-51767 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2026-06-02 N/A 7.0 HIGH
OpenSSH through 10.0, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. NOTE: this is disputed by the Supplier, who states "we do not consider it to be the application's responsibility to defend against platform architectural weaknesses."
CVE-2025-6170 2 Redhat, Xmlsoft 4 Enterprise Linux, Jboss Core Services, Openshift Container Platform and 1 more 2026-06-02 N/A 2.5 LOW
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
CVE-2025-26597 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-02 N/A 7.8 HIGH
A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.
CVE-2026-9149 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-06-02 N/A 6.5 MEDIUM
A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).
CVE-2018-3639 12 Arm, Canonical, Debian and 9 more 321 Cortex-a, Ubuntu Linux, Debian Linux and 318 more 2026-05-29 2.1 LOW 5.5 MEDIUM
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.
CVE-2016-2183 6 Cisco, Nodejs, Openssl and 3 more 9 Content Security Management Appliance, Node.js, Openssl and 6 more 2026-05-29 5.0 MEDIUM 7.5 HIGH
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
CVE-2021-4104 4 Apache, Fedoraproject, Oracle and 1 more 46 Log4j, Fedora, Advanced Supply Chain Planning and 43 more 2026-05-28 6.0 MEDIUM 7.5 HIGH
JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.
CVE-2026-48864 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-05-28 N/A 7.8 HIGH
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
CVE-2019-7317 11 Canonical, Debian, Hp and 8 more 33 Ubuntu Linux, Debian Linux, Xp7 Command View and 30 more 2026-05-28 2.6 LOW 5.3 MEDIUM
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.
CVE-2019-6109 9 Canonical, Debian, Fedoraproject and 6 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2026-05-28 4.0 MEDIUM 6.8 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.
CVE-2019-11135 9 Canonical, Debian, Fedoraproject and 6 more 304 Ubuntu Linux, Debian Linux, Fedora and 301 more 2026-05-28 2.1 LOW 6.5 MEDIUM
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.
CVE-2014-3566 11 Apple, Debian, Fedoraproject and 8 more 20 Mac Os X, Debian Linux, Fedora and 17 more 2026-05-28 4.3 MEDIUM 3.4 LOW
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.
CVE-2015-2808 9 Canonical, Debian, Fujitsu and 6 more 99 Ubuntu Linux, Debian Linux, Sparc Enterprise M3000 and 96 more 2026-05-28 5.0 MEDIUM 3.7 LOW
The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the "Bar Mitzvah" issue.
CVE-2022-3775 2 Gnu, Redhat 2 Grub2, Enterprise Linux 2026-05-27 N/A 7.1 HIGH
When rendering certain unicode sequences, grub2's font code doesn't proper validate if the informed glyph's width and height is constrained within bitmap size. As consequence an attacker can craft an input which will lead to a out-of-bounds write into grub2's heap, leading to memory corruption and availability issues. Although complex, arbitrary code execution could not be discarded.
CVE-2015-8553 2 Redhat, Xen 2 Enterprise Linux, Xen 2026-05-26 2.1 LOW 6.5 MEDIUM
Xen allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory by not enabling memory and I/O decoding control bits. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-0777.
CVE-2026-35092 2 Corosync, Redhat 3 Corosync, Enterprise Linux, Openshift 2026-05-26 N/A 7.5 HIGH
A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol (UDP) packets. This can cause the service to crash, leading to a denial of service. This vulnerability specifically affects Corosync deployments configured to use totemudp/totemudpu mode.
CVE-2026-35091 2 Corosync, Redhat 3 Corosync, Enterprise Linux, Openshift 2026-05-26 N/A 8.2 HIGH
A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory contents
