CVE-2026-103932 1 Modsecurity 1 Modsecurity 2026-11-05 5.8 Medium
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. From 3.0.5 until 3.0.17, the PCRE2 implementation of @rxGlobal in src/utils/regex.cc converts pcre2_match match-limit errors into an ordinary no-match result instead of propagating a non-OK RegexResult. When attacker-controlled input exhausts SecPcreMatchLimit, rules that rely on MSC_PCRE_LIMITS_EXCEEDED or its TX compatibility indicator do not run, so a request that should be rejected can pass through the WAF. The issue affects PCRE2 deployments that use @rxGlobal with a limit-exhaustible expression and a compensating rule; it is not a universal WAF bypass. This issue is fixed in version 3.0.17.
CVE-2026-16277 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-11-05 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-2026-16118 1 Redhat 11 Ai Inference Server, Cert Manager, Cost Management On Premise and 8 more 2026-11-05 7.1 High
A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption.
CVE-2026-15813 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-11-05 6.5 Medium
A vulnerability was found in the network packet de-fragmentation engine of kronosnet (Version affected <= 1.34). The internal reassembly code does not properly validate sequence numbers of incoming payload fragments. An attacker can exploit this lack of verification by transmitting malformed packets with corrupted sequence parameters. Under specific conditions, this forces the packet processing layer to parse data outside the designated bounds of the internal memory structures, causing an out-of-bounds memory access or heap corruption. This behavior can result in sudden application crashes or system instability.
CVE-2026-15779 2 Redhat, Samba 3 Enterprise Linux, Rhel Els, Samba 2026-11-05 6.1 Medium
A flaw was found in samba's pam_winbind. When mkhomedir is enabled, pam_winbind chowns the target account's home directory without validating the path is not a critical system directory such as /. On affected systems, accounts with / as their home directory (a common default for system accounts) can have this triggered not only by root, but by a non-root user holding a narrow sudo delegation to run commands as that account, causing ownership of / to change and resulting in severe denial of service (SSH, sudo, and package-manager failures). The change does not grant write access to / (which ships with restrictive 0555 permissions on RHEL), so the impact is availability loss rather than further privilege escalation.
CVE-2026-15714 2 Libsoup, Redhat 3 Libsoup, Enterprise Linux, Rhel Els 2026-11-05 6.5 Medium
An out-of-bounds read vulnerability was found in libsoup's multipart processing subsystem. The flaw exists in the soup_multipart_input_stream_read_headers() function inside soup-multipart-input-stream.c, which does not adequately restrict or validate the size of incoming multipart boundary strings. When processing a crafted HTTP response containing a malformed or oversized boundary parameter, the internal stream reader reads past the allocated buffer bounds. A remote, unauthenticated attacker can exploit this behavior to cause a service denial (DoS) through application failure or potentially read fragments of unauthorized memory metadata.
CVE-2026-121245 1 Google 1 Chrome 2026-11-05 5.3 Medium
Race condition in Autofill in Google Chrome prior to 157.0.8103.38 allowed a remote attacker to potentially obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-15711 2 Libsoup, Redhat 9 Libsoup, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-05 7.5 High
A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames (e.g., PING, PONG, CLOSE) contain a payload of 125 bytes or less. A remote, unauthenticated attacker can exploit this by sending a non-compliant, oversized control frame. Because the parser handles this protocol violation improperly instead of throwing an immediate connection termination error, it triggers a internal processing crash, resulting in a remote denial of service (DoS) for applications utilizing libsoup WebSockets.
CVE-2026-15709 2 Libsoup, Redhat 9 Libsoup, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-05 7.5 High
A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop (inflate()) processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via max_incoming_payload_size, it fails to track or limit memory allocation during decompression. A separate check for decompressed size (max_total_message_size) exists but executes only after inflation is complete, and it is entirely disabled by default for client connections. A remote, unauthenticated attacker can exploit this by sending a small, highly compressed payload (a decompression bomb), causing unbounded memory allocation that triggers an Out-of-Memory (OOM) crash and a Denial of Service (DoS).
CVE-2026-15588 1 Redhat 18 Ai Inference Server, Cert Manager, Discovery and 15 more 2026-11-05 5.3 Medium
A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.
CVE-2026-121254 1 Google 1 Chrome 2026-11-05 6.5 Medium
Information leak in Select in Google Chrome prior to 157.0.8103.38 allowed a remote attacker to obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-15370 2 Libssh, Redhat 12 Libssh, Enterprise Linux, Enterprise Linux For Els and 9 more 2026-11-05 6.7 Medium
A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead to crashes or possible code execution on the server.
CVE-2026-15028 1 Redhat 5 Cost Management On Premise, Enterprise Linux, Hummingbird and 2 more 2026-11-05 3.9 Low
A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.
CVE-2026-15003 2 Gnu, Redhat 7 Binutils, Enterprise Linux, Hardened Images and 4 more 2026-11-05 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-2026-14969 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2026-11-05 4.4 Medium
A flaw was found in 389-ds-base where the LDBM backend attribute encryption uses a hardcoded static initialization vector for AES-CBC and 3DES-CBC operations, allowing an attacker with privileged filesystem access to detect plaintext equality across encrypted entries by comparing ciphertext blocks.
CVE-2026-14940 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2026-11-05 5.3 Medium
A heap-buffer-overflow flaw was found in 389 Directory Server (389-ds-base). When normalizing a Distinguished Name (DN) that contains a legacy-quoted value encoding a multivalued nested Relative Distinguished Name (RDN), the server can write past the end of a heap allocation while sorting RDN attribute-value pairs. An unauthenticated remote attacker can trigger this condition by sending an LDAP operation whose DN reaches the DN normalization routine, such as a search with a crafted base DN. This can corrupt heap memory and may cause denial of service.
CVE-2026-121252 1 Google 1 Chrome 2026-11-05 8.8 High
Incorrect authorization in Core in Google Chrome prior to 157.0.8103.38 allowed a remote attacker to bypass web origin policy via a crafted HTML page. (Chromium security severity: Low)
CVE-2026-121251 1 Google 1 Chrome 2026-11-05 8.8 High
Missing authorization in V8 in Google Chrome prior to 157.0.8103.38 allowed a remote attacker to bypass web origin policy via a crafted HTML page. (Chromium security severity: Low)
CVE-2026-14476 2 Redhat, Sssd 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-11-05 8 High
A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass.
CVE-2026-121250 1 Google 1 Chrome 2026-11-05 9.6 Critical
Use after free in Extensions in Google Chrome prior to 157.0.8103.38 allowed a remote attacker leveraging social engineering to potentially execute arbitrary code outside the sandbox via a crafted Chrome extension. (Chromium security severity: High)
