CVE-2026-16277 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-08-02 6.5 Medium
A stack-based buffer overflow was found in rpcbind's rpcinfo utility. When querying a remote rpcbind service with `rpcinfo -l`, address information returned by the server is copied into a fixed-size buffer without sufficient bounds checking. A malicious or compromised rpcbind server could use this flaw to crash the rpcinfo client, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2026-6390 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-08-02 6.8 Medium
A flaw was found in GNU nano's multi-buffer error message handling. When a user opens multiple files at startup and one triggers an ALERT-level error, a specially crafted filename containing printf format specifiers can be reinterpreted. This format string vulnerability may allow an attacker to achieve stack information disclosure, cause a denial of service (crash), or potentially perform arbitrary memory writes.
CVE-2026-58216 2 Redhat, Samba 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-07-31 5.3 Medium
An out-of-bounds read flaw was found in Samba's Kerberos Key Distribution Center's (KDC) password change (kpasswd) service. When processing malformed ASN.1-encoded Kerberos password change request, Samba server miscalculates the structure size and attempts to read up to six bytes beyond the end of the allocated buffer. While this out-of-bounds read typically results in a harmless decryption failure, if the read hits unmapped memory, it causes the KDC process to crash. An authenticated attacker can send a specially crafted kpasswd request containing malformed ASN.1 data to trigger the out-of-bounds read, which may cause the KDC process to terminate, resulting in a denial of service.
CVE-2026-9150 3 Opensuse, Red Hat, Redhat 11 Libsolv, Red Hat Satellite 6, Enterprise Linux and 8 more 2026-07-31 6.5 Medium
A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.
CVE-2026-9149 3 Opensuse, Red Hat, Redhat 12 Libsolv, Red Hat Satellite 6, Enterprise Linux and 9 more 2026-07-31 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-2026-58218 2 Redhat, Samba 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-07-30 5.3 Medium
A flaw was found in Samba's internal DNS server where unauthenticated TKEY registration requests were added to the TKEY name cache before being rejected. A remote, unauthenticated attacker can exploit this behavior by sending a large number of TKEY requests with arbitrary names, exhausting the cache and evicting legitimate TKEY entries. This can prevent legitimate TSIG authentication for signed DNS queries, resulting in a denial of service.
CVE-2026-58222 2 Redhat, Samba 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-07-30 8.8 High
A security flaw combining LDAP filter injection and improper authorization checks was found in Samba Active Directory Domain Controller (AD DC). When processing LDAP Compare requests, Samba fails to properly validate user-supplied attribute names and executes the resulting internal database search in a trusted context, bypassing normal Access Control List (ACL) enforcement. An authenticated low-privilege domain user can exploit these flaws to disclose confidential Active Directory attributes that would normally be inaccessible. The disclosed information may be leveraged to derive sensitive authentication material, potentially leading to privilege escalation and complete domain compromise. For example: In deployments configured with Group Managed Service Accounts (gMSAs), an attacker can extract the "msKds-RootKeyData" attribute and derive gMSA passwords offline, potentially leading to complete domain compromise if privileged gMSAs are present.
CVE-2026-18220 2 Gnu, Redhat 6 Binutils, Enterprise Linux, Hardened Images and 3 more 2026-07-30 7.8 High
An out-of-bounds write vulnerability was found in the BFD library's DLX ELF backend (bfd/elf32-dlx.c) in GNU binutils. The dlx_rtype_to_howto() function maps ELF relocation types to internal howto structures but fails to perform adequate bounds checking on attacker-controlled relocation type values (via ELF32_R_TYPE(r_info)) before indexing into the dlx_elf_howto_table[] array. The DLX relocation type number space is non-contiguous (basic types 0-6, extended types at 0x10000+), but the default case in the switch statement allows arbitrary index values to reach the array access. A specially crafted ELF/DLX object file can trigger this out-of-bounds write when processed by any BFD-consuming tool (objdump, readelf, strip, ld, nm, objcopy). The vulnerability has been demonstrated to achieve arbitrary code execution via a File Stream Oriented Programming (FSOP) attack against glibc FILE structures (stderr), redirecting control flow to system(). Attack scenarios include CI/CD pipelines performing automated binary analysis, developer workstations running objdump/readelf on untrusted binaries, automated security scanning or malware analysis tools invoking binutils, and package build systems processing third-party code. Note: This vulnerability is only exploitable when binutils is built with the DLX backend enabled (typically via --enable-targets=all).
CVE-2026-16531 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-07-30 5.3 Medium

CVE-2026-4948 2 Firewalld, Redhat 5 Firewalld, Enterprise Linux, Firewalld and 2 more 2026-07-30 5.5 Medium
A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.
CVE-2026-15003 2 Gnu, Redhat 6 Binutils, Enterprise Linux, Hardened Images and 3 more 2026-07-28 5.6 Medium
A flaw was found in the GNU Binutils (Binary Utilities) linker. This vulnerability, a heap-buffer-overflow read (CWE-125), occurs when the linker processes a specially crafted 32-bit XCOFF (Extended Common Object File Format) object file. An attacker could exploit this by providing a malicious file, leading to an out-of-bounds read of memory. This can result in information disclosure, potentially revealing sensitive heap data, and a Denial of Service (DoS) due to the linker crashing.
CVE-2026-16517 2 Libarchive, Redhat 6 Libarchive, Enterprise Linux, Hardened Images and 3 more 2026-07-27 2.9 Low
A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption.
