CVE-2026-89078 1 Gitlab 1 Gitlab 2026-09-24 9.9 Critical
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 before 19.2.7, 19.3 before 19.3.3, and 19.4 before 19.4.1 that under certain conditions could have allowed an authenticated user to execute arbitrary code on the GitLab server due to a double free issue when parsing a specially crafted regular expression in a CI/CD configuration.
CVE-2026-6794 1 Ibm 1 Concert 2026-09-24 7.8 High
IBM Concert 1.0.0 through 3.0.0 has a double free vulnerability that exists due to incorrect memory management. A local attacker can exploit this flaw to corrupt heap memory and execute arbitrary code in the context of the affected process.
CVE-2026-14164 3 Libarchive, Red Hat, Redhat 12 Libarchive, Enterprise Linux, Discovery and 9 more 2026-09-24 7.5 High
A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.
CVE-2026-75159 1 Mongodb 1 Bi Connector 2026-09-23 5.9 Medium
An unauthenticated client that can reach a MongoDB Connector for BI deployment configured with Kerberos authentication may cause mongosqld to terminate when a crafted authentication exchange encounters a specific GSSAPI error-handling condition. This can interrupt BI Connector availability until the process restarts.
CVE-2026-18798 1 Openssl 1 Openssl 2026-09-23 7.5 High
Issue summary: QUIC server may double free QRX (QUIC record layer RX) object when channel creation fails for initial packet. Impact summary: Double free leads to heap corruption, which typically results in termination of QUIC server process, leading to Denial of Service. There is so far no evidence that this double free is exploitable for remote code execution, thus it is considered highly improbable. CWE: CWE-415: Double Free Description: In order to validate initial packet, OpenSSL QUIC stack default packet handler (port_default_packet_handler()) creates a so-called QRX object. If the initial packet validates successfully with QRX object, the default packet handler proceeds to channel (connection object) creation. The QRX object used for packet validation is passed to port_bind_channel(), so it becomes part of the newly created connection. If port_bind_channel() fails, then it also frees the QRX object. Once port_bind_channel() returns, the port_default_packet_handler() detects the failure and proceeds to the error branch, where the same QRX object is freed for the second time. The failure in port_bind_channel() function can be induced with a relatively low effort by a malformed (non RFC 9000 compliant) INITIAL packet. If the packet carries DCID (destination connection ID) which is shorter than 8 bytes, then port_bind_channel() jumps to the error path after ossl_quic_lcidm_enrol_odcid() detects that the DCID has invalid length. FIPS impact: no The FIPS module is not affected, as the QUIC implementation is outside of the OpenSSL FIPS module boundary.
CVE-2026-91018 1 Lwip 1 Lwip 2026-09-23 8.8 High
lwIP (Lightweight IP) has a double free vulnerability, which could crash the system, cause a DoS, memory corruption, or allow code execution on the victim system.

CVE-2026-11388 1 Rti 1 Connext Professional 2026-09-22 N/A
Double Free vulnerability in RTI Connext Professional (Core Libraries) allows File Manipulation. This issue affects Connext Professional: from 7.4.0 before 7.7.0.1, from 7.1.0 before 7.3.1.6.
CVE-2026-63652 1 Freerdp 1 Freerdp 2026-09-22 6.5 Medium
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, rdpsnd_server_recv_formats in channels/rdpsnd/server/rdpsnd_main.c frees context->client_formats on a malformed Client Audio Formats PDU without clearing the owning pointer or num_client_formats. An authenticated RDP client can trigger an error such as a cbSize larger than the remaining record, leave the dangling pointer in the server context, and cause rdpsnd_server_context_free to free the same allocation again at session teardown. This reliably terminates the server and can create allocator-dependent heap corruption. This issue is fixed in version 3.28.0.
CVE-2026-71351 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-22 7 High

CVE-2026-84964 1 Mongodb 1 C Driver 2026-09-22 5.9 Medium
A double free in the OpenSSL-based TLS certificate revocation checking path of the MongoDB C Driver can be reached by a TLS endpoint that the client already trusts. During the handshake, specially formed certificate data can cause the same heap object to be released twice. An unauthenticated party acting as the trusted endpoint may cause the connecting client application to terminate unexpectedly.
CVE-2026-58381 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-09-22 6.1 Medium
A flaw was found in GIMP's PSP file format parser. A double-free condition occurs in the read_layer_block() function when processing a specially crafted PSP file. This could allow an attacker to cause memory corruption, potentially leading to denial of service or arbitrary code execution.
CVE-2026-17050 1 Zephyrproject 1 Zephyr 2026-09-21 5.7 Medium
The experimental USB host stack allocates a per-device configuration-descriptor buffer, udev->cfg_desc, from the dedicated usb_device_heap in usbh_device_set_configuration() (subsys/usb/host/usbh_device.c). On three failure paths — a failed full-length GET_DESCRIPTOR(CONFIGURATION) read, a mismatch between the short and full descriptor reads, and a rejected descriptor in parse_configuration_descriptor() — the buffer was released with k_heap_free() but the pointer was left dangling. The cleanup in usbh_device_free() is guarded only by if (udev->cfg_desc != NULL), so it frees the same block a second time. The path is driven entirely by the attached peripheral: usbh_device_connect() calls usbh_device_init(), which ends in usbh_device_set_configuration(), and on failure usbh_device_connect() calls usbh_device_free(). On v4.4.x this happens during the same enumeration, with no unplug required; on v4.1.0–v4.3.x the second free instead arrives via dev_removed_handler()/dev_connected_handler() in subsys/usb/host/usbh_core.c, so it requires a removal or duplicate-connect event after the failed enumeration — a sequence the attached device fully controls. A malicious or malformed USB device only has to answer the first 9-byte configuration-descriptor request with a well-formed header and then fail any of the three checks, for example by returning a full descriptor whose interface count disagrees with bNumInterfaces, or by answering the second read with different bytes. The result is a double free on usb_device_heap. On builds where lib/heap hardening is active (the current default CONFIG_SYS_HEAP_HARDENING_BASIC), sys_heap_free() detects the already-free chunk and calls k_panic(), giving a deterministic, peripheral-triggered denial of service of the USB host. On builds without that detection — earlier releases, or CONFIG_SYS_HEAP_HARDENING_NONE — the second free manipulates a chunk already on the free list, corrupting the heap's free list so that later allocations can return overlapping or invalid blocks. Exploitation beyond denial of service is bounded by the fact that usb_device_heap is a small dedicated heap (CONFIG_USBH_USB_DEVICE_HEAP, default 1024 bytes) whose only client is this descriptor buffer, and by CONFIG_USB_HOST_STACK being marked experimental and disabled by default. The fix sets udev->cfg_desc = NULL after every k_heap_free(), making the cleanup guard sound.
