The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O (CVE-2025-40026) * kernel: dlm: validate length in dlm_search_rsb_tree (CVE-2026-43125) * kernel: xen: AMD Zen 2 Processors: Privilege escalation via improper CPU cache isolation (CVE-2025-54518) * kernel: selinux: fix overlayfs mmap() and mprotect() access checks (CVE-2026-46054) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Samba is an open-source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information. Security Fix(es): * samba: Missing access check on reparse point operations (CVE-2026-1933) * samba: vfs_worm does not block directory modification (CVE-2026-2340) * samba: group policy certificate enrollment uses http:// without validation (CVE-2026-3012) * samba: Samba: Remote Code Execution in printing subsystem via unescaped job description (CVE-2026-4480) * samba: Remote Code Execution in SAMR (CVE-2026-4408) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.

A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install it into the local trust store without proper verification. An attacker with the ability to intercept or redirect network traffic could exploit this behavior to supply a malicious certificate authority certificate, potentially allowing interception or spoofing of trusted communications.

BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. BIND includes a DNS server (named), which resolves host names to IP addresses; a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating properly. Security Fix(es): * bind: BIND: Denial of Service via maliciously crafted DNSSEC-validated zone (CVE-2026-1519) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
