| CVE-2026-119727 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-05 | 6.5 Medium |
| A flaw was found in GStreamer's gst-plugins-bad H.265 video parser. When parsing a specially crafted H.265 bitstream containing a Screen Content Coding (SCC) extension with certain palette predictor initializer settings, an integer underflow in the upper-bound computation allows the parser to accept an out-of-range value for the number of palette predictor entries. This causes the parser to write beyond the end of a fixed-size array, resulting in memory corruption and an application crash. An attacker can deliver the malformed bitstream as a local file or over a network stream such as HTTP, HLS, DASH, RTSP, RTP, or WebRTC. Successful exploitation requires the application to open or play that content, and is limited to a denial-of-service impact. | ||||
| CVE-2026-12725 | 3 Dnsmasq, Redhat, Thekelleys | 6 Dnsmasq, Enterprise Linux, Openshift and 3 more | 2026-11-05 | 5.9 Medium |
| A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both enabled, logging of DS or DNSKEY replies containing unsupported algorithm or digest types can cause dnsmasq to write past the end of an internal logging buffer. A remote attacker able to supply such a DNS response may crash the dnsmasq process, resulting in denial of service. | ||||
| 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-2026-11884 | 1 Redhat | 4 Directory Server, Enterprise Linux, Redhat Directory Server and 1 more | 2026-11-05 | 6.5 Medium |
| A heap buffer overflow flaw was found in 389 Directory Server. When serializing objectclass definitions, the oc_superior (SUP) field length is omitted from buffer size calculations in read_schema_dse() and schema_oc_to_string(), but the field is still written via strcat(). An attacker with Directory Manager privileges, or a compromised replication supplier, can trigger a server crash by creating objectclasses with long SUP values. This is an incomplete fix variant of CVE-2025-14905. | ||||

| CVE-2025-14905 | 1 Redhat | 12 Directory Server, Directory Server E4s, Directory Server Eus and 9 more | 2026-11-05 | 7.2 High |
| A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE). | ||||
| CVE-2025-14087 | 2 Gnome, Redhat | 17 Glib, Ai Inference Server, Cert Manager and 14 more | 2026-11-05 | 5.6 Medium |
| A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings. | ||||
| CVE-2024-56827 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-05 | 5.6 Medium |
| A flaw was found in the OpenJPEG project. A heap buffer overflow condition may be triggered when certain options are specified while using the opj_decompress utility. This can lead to an application crash or other undefined behavior. | ||||
| CVE-2024-56826 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-05 | 5.6 Medium |

| CVE-2024-1062 | 2 Fedoraproject, Redhat | 17 Fedora, 389 Directory Server, Directory Server and 14 more | 2026-11-05 | 5.5 Medium |
| A heap overflow flaw was found in 389-ds-base. This issue leads to a denial of service when writing a value larger than 256 chars in log_entry_attr. | ||||
| CVE-2026-62365 | 1 Wazuh | 1 Wazuh | 2026-11-05 | 5.3 Medium |
| Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. DecodeWinevt in src/analysisd/decoders/winevtchannel.c accumulates unnamed Windows EventChannel Data element contents into the fixed 65,535-byte join_data heap buffer but passes the growing content length, rather than the OS_MAXSTR buffer capacity, as the snprintf size. An enrolled agent can submit an EventChannel message containing four maximum-sized unnamed Data elements, causing the fourth accumulation to write beyond join_data and corrupt adjacent heap metadata. The subsequent free of join_data2 causes the wazuh-analysisd process to terminate, stopping log ingestion for all agents handled by that manager. This vulnerability is fixed in 4.14.7. | ||||
| CVE-2026-84268 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more | 2026-11-04 | 8.8 High |
| A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution. | ||||
| CVE-2026-6846 | 3 Gnu, Iputils, Redhat | 8 Binutils, Iputils, Enterprise Linux and 5 more | 2026-11-04 | 7.8 High |
| A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable. | ||||
| CVE-2026-58379 | 2 Gimp, Redhat | 7 Gimp, Enterprise Linux, Enterprise Linux Eus and 4 more | 2026-11-04 | 7.3 High |
| A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory. | ||||
| CVE-2026-56208 | 2 Aomedia, Redhat | 14 Libaom, Ai Inference Server, Enterprise Linux and 11 more | 2026-11-04 | 7.6 High |
| A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing (LAP) mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when g_lag_in_frames is set to 1 or higher. This results in a 232-byte out-of-bounds write on every encoded frame after the second, corrupting adjacent heap objects. An attacker who can influence encoder configuration in a transcoding service or WebRTC session could exploit this to cause a denial of service (process crash) or potentially achieve code execution. | ||||
| CVE-2026-52720 | 2 Gstreamer Project, Redhat | 9 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-11-04 | 8.8 High |
| A heap buffer overflow vulnerability was found in GStreamer's librfb (RFB/VNC client). The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a malicious VNC server and trick a user into connecting, resulting in an out-of-bounds heap write that could lead to code execution or a crash. | ||||
