High [CVE-2026-73142] Unbounded resource exhaustion via connection object leak in NetUplink
A flaw was found in svxlink's remotetrx NetUplink component. When a server initiates a disconnect, the associated connection object is not properly freed, causing a memory leak. A remote attacker can repeatedly trigger disconnects to cause unbounded memory growth, leading to a denial of service. svxlink is not shipped in any Red Hat Enterprise product. It is available in Fedora as a community-maintained package. Red Hat severity: Important. Weakness: CWE-401.
High [CVE-2026-73143] Denial of service via malformed rtl_tcp greeting
A flaw was found in svxlink's RtlTcp component. A malformed rtl_tcp greeting from a remote source triggers an unconditional exit(1) call, causing the entire svxlink daemon to terminate. A remote attacker can exploit this to achieve a complete denial of service of the repeater controller. svxlink is not shipped in any Red Hat Enterprise product. It is available in Fedora as a community-maintained package. Red Hat severity: Important. Weakness: CWE-617.
Medium [CVE-2026-47143] Denial of Service vulnerability via crafted input
Capstone is a disassembly framework. Versions prior to 6.0.0-Alpha8 and 5.0.8 have a NULL pointer dereference in `modRMRequired()` and `decode()` when disassembling 3DNow! opcodes (`0F 0F`) in builds compiled with `-DCAPSTONE_X86_REDUCE`, allowing a remote attacker to crash any application using the reduced X86 Capstone library by supplying a crafted input containing the 4-byte sequence `0F 0F `. This vulnerability only affects builds compiled with the -DCAPSTONE_X86_REDUCE flag; standard full builds are not vulnerable. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-476. Affected Red Hat products: Red Hat Hardened Images. Red Hat fixing advisory: RHSA-2026:43841.

Medium [CVE-2026-47021] Enhance XBM image support (Oracle CPU 2026-07)
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: 2D). Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). A flaw was found in OpenJDK. The regex defined in XbmImageDecoder (matchRegex) is vulnerable to a DoS attack when the input contains a long string without a closing character; due to excessive backtracking. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-1333. Affected products named by the advisory: OPENJDK ELS 11.0.32; Red Hat Build of OpenJDK 17.0.20; Red Hat Build of OpenJDK 21.0.12; Red Hat Build of OpenJDK 25.0.4; and 21 more.
Medium [CVE-2026-47027] Enhance Jar file processing (Oracle CPU 2026-07)
Vulnerability in Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and 21.0.11; Oracle GraalVM Enterprise Edition: 21.3.18. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). A flaw was found in OpenJDK. The processImpl() method in SignatureFileVerifier exhibits O(n^2) time complexity when verifying JAR files where different entries have different signer combinations, potentially leading to DoS. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
Medium [CVE-2026-60147] Improve certification checking (Oracle CPU 2026-07)
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Security). Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 6.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N). A flaw was found in OpenJDK. OpenJDK can apply two different security meanings to the same wildcard dNSName SAN across certificate policy enforcement and hostname verification. During path validation, DNSName.constrains compares *.foo.com and secret.foo.com literally and returns NAME_SAME_TYPE, so NameConstraintsExtension.verify does not reject the chain when secret.foo.com is an exact-host exclusion. Later, HostnameChecker interprets the same SAN as a wildcard template and accepts secret.foo.com for *.foo.com. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N). Weakness: CWE-295.
Medium [CVE-2026-12548] heap out-of-bounds read in libsoup due to integer truncation
A heap out-of-bounds read flaw was found in libsoup. When parsing multipart HTTP messages, an integer type mismatch between the caller and soup_headers_parse() can cause the length parameter to be incorrectly truncated, leading to a heap buffer over-read. A remote attacker could use this flaw to crash an application using libsoup or potentially disclose heap memory contents. Red Hat severity: Moderate — CVSS 4.2 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: libsoup3.

Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 10.
Medium [CVE-2026-59850] use-after-free via data callbacks on closed channels
A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions.
