Red Hat released Important security updates for OpenSSL in Red Hat Enterprise Linux 9 and Red Hat Enterprise Linux 10, fixing a broad set of flaws that could lead to remote code execution, arbitrary code execution, denial of service, information disclosure, data tampering, and data integrity bypass. The updates, published as RHSA-2026:1473 for RHEL 9 and RHSA-2026:1472 for RHEL 10, cover twelve CVEs across PKCS#12 processing, CMS parsing, QUIC handling, TLS 1.3 certificate compression, BIO filtering, OCB encryption and decryption calls, TimeStamp Response parsing, and PKCS#7 signature verification, with updated package version 3.5.1-7 issued for supported architectures and product variants.

Red Hat released **Important** security updates for OpenSSL across multiple **RHEL 9** and **RHEL 10** channels to address two high-impact vulnerabilities, **`CVE-2025-15467`** and **`CVE-2025-69419`**. The first flaw affects parsing of CMS `AuthEnvelopedData` with AEAD ciphers, where an oversized initialization vector can overflow a fixed-size stack buffer before authentication or tag verification, creating a path to denial of service and possible remote code execution. The second flaw is a memory corruption bug in PKCS#12 processing, where `BMPString` to UTF-8 conversion can trigger an out-of-bounds heap write when an application parses an attacker-controlled PKCS#12 file, potentially causing a crash or arbitrary code execution. Upstream fixes were issued in OpenSSL **3.0.19**, **3.3.6**, **3.4.4**, **3.5.5**, **3.6.1**, and **1.1.1ze** for the affected branches, while OpenSSL **1.0.2** is not affected and the OpenSSL FIPS modules are outside the vulnerable code paths. Red Hat advisories including **RHSA-2026:1496**, **RHSA-2026:1503**, **RHSA-2026:1519**, **RHSA-2026:1594**, and **RHSA-2026:1733** cover impacted products such as RHEL 9.0, 9.2, 9.4, 9.6, and 10.0 variants, along with related SAP, AUS, EUS, OpenShift, and JBoss Core Services offerings, with updated package builds released for major architectures including `x86_64`, `aarch64`, `ppc64le`, and `s390x`.

Red Hat released **Important** security updates for the Linux kernel across **RHEL 8, RHEL 9, and RHEL 10**, including `kernel-rt` for Real Time deployments, fixing vulnerabilities in core subsystems such as **SMB/CIFS client code, iSCSI target handling, SMC, `sched/psi`, `memfd`, UDF, netfilter, POSIX CPU timers, and AMD GPU drivers**. The advisories cover **nine CVEs in RHEL 8**, **26 CVEs in RHEL 9**, and **24 CVEs in RHEL 10**, with affected offerings spanning standard, Extended Life Cycle, Extended Update Support, SAP, NFV, and CodeReady Linux Builder channels across **x86_64, s390x, ppc64le, and aarch64**. Red Hat said systems should be **rebooted after applying the updates** and reiterated that kernel errata should be treated as security-relevant because of the kernel’s central role. Among the patched flaws, Red Hat detailed **`CVE-2026-53143`**, a **buffer overflow** in the `drm/amdkfd` driver on **GFX11** that could leak or corrupt adjacent GTT memory during CRIU checkpoint and restore operations because SDMA queues used compute-specific handlers with the wrong MQD size. The company also fixed **`CVE-2026-63952`** in **`memfd`**, where writable mappings could persist even when `SEAL_EXEC` implicitly applied `SEAL_WRITE`, weakening the expected write-seal guarantees and undermining **W^X** protections. The RHEL 9 advisory also includes non-security fixes, including a regression in `5.14.0-687.5.1.el9_8` that broke Wi-Fi when **FIPS** was enabled.

Red Hat released **Important** security updates for Go packages in **Red Hat Enterprise Linux 9** and **Red Hat Enterprise Linux 10**, addressing **CVE-2026-27137** and **CVE-2026-25679** across multiple architectures and support channels. The advisories, `RHSA-2026:19181` for RHEL 9 and `RHSA-2026:19022` for RHEL 10, update Go to `1.26.2+2` in the RHEL 9.8.z stream and `1.26.2-2.el10_2` in RHEL 10.2, with packages provided for `x86_64`, `s390x`, `ppc64le`, and `aarch64` systems, including Extended Update Support and Extended Life Cycle offerings. The more detailed flaw, **CVE-2026-25679**, affects Go's `net/url.Parse` function, which can incorrectly accept malformed URLs by failing to properly validate the host or authority component and by treating garbage before an IPv6 literal as ignorable. Red Hat rated that issue **Important** with a **CVSS 7.5** score and said no qualifying mitigation was available, while the second bug, **CVE-2026-27137**, affects Go's `crypto/x509` handling of email constraints. Organizations running Go workloads or development toolchains on supported RHEL releases should prioritize the updated `golang` and `go-toolset` packages to close both parsing and certificate-validation exposure.
