CVE-2026-88833 2 Busybox, Redhat 3 Busybox, Hummingbird, Rhel Els 2026-11-09 6.5 Medium
A flaw was found in BusyBox's udhcpc DHCP client. When processing raw DHCP packets, the client replaces the validated packet length with an attacker-controlled value from the IP header without re-validating the minimum size. This leads to an integer underflow when subtracting header sizes, causing a subsequent memory copy with a massively oversized length. An attacker on the same network segment can send a specially crafted packet to crash the DHCP client, resulting in denial of service and loss of network connectivity.
CVE-2026-13595 3 Kernel, Linux, Redhat 10 Util-linux, Util-linux, Cost Management On Premise and 7 more 2026-11-09 6.8 Medium
A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug events. This could lead to limited information disclosure or denial of service.
CVE-2026-13732 1 Redhat 9 Cost Management On Premise, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-09 7 High
A flaw was found in GDB's STABS debug format parser. The read_member_functions() function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main function list while the list length counter is decremented, resulting in an out-of-bounds write when the function list is copied to its final allocated array. An attacker can craft an ELF binary with malicious .stab and .stabstr sections that triggers this out-of-bounds write when a user opens the file in GDB and performs any symbol-inspection operation such as setting a breakpoint. The inferior process does not need to be executed. Under controlled conditions, this was demonstrated to achieve execution of arbitrary commands within the GDB process.
CVE-2026-87876 2 Openprinting, Redhat 7 Cups, Enterprise Linux, Hardened Images and 4 more 2026-11-06 3 Low
Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations.
CVE-2026-85498 2 Polkit Project, Redhat 5 Polkit, Enterprise Linux, Hummingbird and 2 more 2026-11-06 3.5 Low
A flaw was found in polkit. When processing input that begins with a null byte, an arithmetic error in the authentication agent helper causes an integer underflow during buffer length calculation, resulting in an out-of-bounds memory read. An attacker capable of supplying crafted input can trigger this flaw, potentially causing an application crash and resulting in a Denial of Service (DoS).
CVE-2026-79699 1 Redhat 7 Ansible Automation Platform, Container Native Virtualization, Enterprise Linux and 4 more 2026-11-06 4.4 Medium
A flaw was found in the containers/storage library. A crafted tar archive containing a malicious whiteout header (e.g. victim/.wh.) can cause the extraction destination directory to be replaced with an arbitrary file when processed by storage/pkg/archive.UnpackLayer, ApplyLayer, or ApplyUncompressedLayer.
CVE-2026-59849 2 Libssh, Redhat 12 Libssh, Enterprise Linux, Enterprise Linux For Els and 9 more 2026-11-06 3.1 Low
A flaw was found in libssh. Logic errors in automatic certificate-based public key authentication can cause libssh clients to loop indefinitely when configured certificates are missing or repeatedly rejected by a server, leading to denial of service.
CVE-2026-59842 2 Libssh, Redhat 12 Libssh, Enterprise Linux, Enterprise Linux For Els and 9 more 2026-11-06 3.7 Low
A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthenticated attacker to disclose small amounts of server memory.
CVE-2026-55654 3 Openbsd, Openssh, Redhat 9 Openssh, Openssh, Enterprise Linux and 6 more 2026-11-06 3.7 Low
A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service.
CVE-2026-5419 2 Gnu, Redhat 14 Gnutls, Cert Manager, Discovery and 11 more 2026-11-06 3.7 Low
A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure.
CVE-2026-3832 2 Gnu, Redhat 11 Gnutls, Cert Manager, Discovery and 8 more 2026-11-06 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-2026-44605 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-11-06 5.5 Medium
A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable.
CVE-2026-3184 3 Kernel, Linux, Redhat 7 Util-linux, Util-linux, Enterprise Linux and 4 more 2026-11-06 3.7 Low
A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.
CVE-2026-18839 2 Popt-devel, Redhat 8 Popt-static, Enterprise Linux, Hardened Images and 5 more 2026-11-06 2.2 Low
An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of service of the affected application.
CVE-2026-18743 2 Redhat, Rpm-software-management 8 Enterprise Linux, Hardened Images, Hummingbird and 5 more 2026-11-06 2.5 Low
A flaw was found in popt. This vulnerability allows an attacker to provide specially crafted configuration content to a host, which, when loaded, can lead to a small memory corruption issue. This occurs because of an error in how the `poptConfigFileToString` function reallocates memory for buffers. Successful exploitation could result in heap metadata corruption, potentially causing the affected process to become unavailable (denial of service).
CVE-2026-18739 2 Popt-devel, Redhat 6 Popt-static, Enterprise Linux, Hummingbird and 3 more 2026-11-06 2.5 Low
A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacker to execute arbitrary code if the host application then unsafely processes the altered data.
CVE-2026-17591 3 Libarchive, Red Hat, Redhat 7 Libarchive, Enterprise Linux, Enterprise Linux and 4 more 2026-11-06 3.6 Low
A flaw was found in libarchive. An attacker can cause a Denial of Service (DoS) or potential information disclosure due to a use-after-free vulnerability, which occurs when a program reads memory that has already been released. This issue arises when the archive_entry_copy_mac_metadata() function deallocates an internal buffer before completing a data copy. An attacker who can supply input to an application utilizing this function can trigger the flaw to crash the application or read uninitialized memory data.
CVE-2026-16517 2 Libarchive, Redhat 7 Libarchive, Enterprise Linux, Hardened Images and 4 more 2026-11-06 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.
CVE-2025-6170 2 Redhat, Xmlsoft 20 Ai Inference Server, Cert Manager, Discovery and 17 more 2026-11-06 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.
