CVE-2026-76957 1 Libexpat Project 1 Libexpat 2026-11-10 4.9 Medium
libexpat before 2.8.4 lacks handler call depth tracking with custom encoding callbacks. Thus, a use-after-free can occur. NOTE: this is similar to CVE-2026-50219, CVE-2026-56131 and CVE-2026-56412.
CVE-2026-66032 2 Libssh2, Redhat 2 Libssh2, Hummingbird 2026-11-10 8.8 High
libssh2 through 1.11.1, fixed in commit 5e47761, contains a double-free vulnerability in the sftp_open() function in src/sftp.c that allows a malicious SSH server to corrupt the heap of any authenticated client opening an SFTP session. When a server responds to SSH_FXP_OPEN with SSH_FXP_STATUS containing FX_OK, the response data buffer is freed, and if a subsequent sftp_packet_require() call returns a specific error such as LIBSSH2_ERROR_CHANNEL_PACKET_EXCEEDED, the same pointer is freed a second time, enabling tcache dup conditions on glibc systems that allow overlapping allocations and function pointer overwrites.
CVE-2026-56412 1 Libexpat Project 1 Libexpat 2026-11-10 4.9 Medium
libexpat before 2.8.2 does not consider XML_TOK_DATA_CHARS in doCdataSection and thus lacks handler call depth tracking for various calls from within handlers in cases of a policy violation. Thus, a use-after-free can occur. NOTE: this issue exists because of an incomplete fix for CVE-2026-50219.
CVE-2026-56131 1 Libexpat Project 1 Libexpat 2026-11-10 4.9 Medium
libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_ResumeParser from within handlers in cases of a policy violation. Thus, a use-after-free can occur (similar to the CVE-2026-50219 situation).
CVE-2026-50219 1 Libexpat Project 1 Libexpat 2026-11-10 4.9 Medium
libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_GetBuffer, XML_Parse, XML_ParseBuffer, XML_ParserFree, or XML_ParserReset from within handlers in cases of a policy violation. Thus, a use-after-free can occur,
CVE-2026-19445 2 Python, Redhat 2 Cpython, Hummingbird 2026-11-10 8.1 High
A remote, unauthenticated TLS client can make a server crash or call through a freed pointer if its sni_callback assigns a different context to SSLSocket.context (the documented way to select a certificate per server name) and nothing else keeps the original ssl.SSLContext alive. Typical cases are servers that create an SSLContext per connection or replace it while connections are open; servers that wrap their listening socket with it are not affected. Mitigation: keep a reference to every SSLContext that sets sni_callback for the lifetime of the server. TLS clients are not affected.
CVE-2026-106175 1 Fortinet 5 Fortios, Fortipam, Fortiproxy and 2 more 2026-11-10 2.1 Low
A Double Free vulnerability [CWE-415] vulnerability in Fortinet FortiOS 7.6.0 through 7.6.8, FortiOS 7.4 all versions, FortiOS 7.2 all versions, FortiOS 7.0 all versions, FortiProxy 7.6.0 through 7.6.6, FortiProxy 7.4 all versions, FortiProxy 7.2 all versions, FortiProxy 7.0 all versions, FortiSwitch 7.6.0 through 7.6.6, FortiSwitch 7.4 all versions, FortiSwitch 7.2 all versions may allow a local authenticated attacker to crash the newcli daemon via crafted CLI commands.
CVE-2026-125704 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-10 7.5 High
A use-after-free flaw was found in GStreamer core buffer value deserialization. When crafted serialized buffer data contains an invalid character, an error path frees a mapped buffer before unmapping it. An application that parses untrusted caps or structure data could crash; a network-facing GStreamer Data Protocol receiver can process such data without user interaction. Further impact has not been established.
CVE-2026-124684 1 Samsung Open Source 1 Escargot 2026-11-10 5.1 Medium
This issue can cause a heap-use-after-free when an embedder unloads a ReloadableString buffer while a previously returned raw character pointer remains in use. Successful triggering may cause the Escargot-based process to crash, resulting in a denial of service.
CVE-2026-113970 1 Apple 4 Ios And Ipados, Macos, Visionos and 1 more 2026-11-10 8.8 High
A use-after-free issue was addressed with improved memory management. This issue is fixed in iOS 18.7.12 and iPadOS 18.7.12, iOS 26.7.3 and iPadOS 26.7.3, iOS 27.2.1 and iPadOS 27.2.1, macOS Golden Gate 27.2.1, macOS Sequoia 15.8.3, macOS Tahoe 26.7.3, visionOS 27.2.1, watchOS 26.6.1, watchOS 27.2.1. An attacker in Bluetooth range may be able to corrupt process memory.
CVE-2026-69150 1 Keepassxc 1 Keepassxc 2026-11-10 N/A
KeePassXC is a cross-platform community-driven port of the Windows application KeePass Password Safe. Prior to 2.8.0-beta1, KeePass1 / KDB legacy import retains raw Entry pointers in m_entryUuids after deleting metastream entries. When a crafted, unlockable .kdb file contains an earlier metastream entry followed by a KPX_CUSTOM_ICONS_4 metastream that references the earlier UUID, parseCustomIcons4() calls Entry::setIcon through the stale pointer, causing a heap use-after-free with a controlled write and a reliable process crash. This issue is fixed in version 2.8.0-beta1.
CVE-2026-125400 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 8.8 High
Ettercap through 0.8.4.1 contains a use-after-free vulnerability in func_pcre() in src/ec_filter.c that reads the PCRE2 ovector after freeing match data. Network-adjacent attackers can send packets matching a loaded pcre_regex() substitution filter to corrupt memory and potentially execute code as root.
CVE-2026-125394 1 Freerdp 1 Freerdp 2026-11-09 5.4 Medium
FreeRDP before 3.33.0 contains a heap use-after-free vulnerability in update_gdi_patblt(), update_gdi_polygon_cb() and update_gdi_mem3blt() that retain stale brush cache pointers. A malicious RDP server can resend CACHE_BRUSH to the same slot then send PATBLT, causing clients to read freed heap memory, disclosing data or crashing.
CVE-2026-124307 1 Fraunhoferhhi 1 Vvdec 2026-11-09 5.8 Medium
Fraunhofer HHI VVdeC before 3.2.1 contains a heap use-after-free vulnerability that allows attackers to corrupt memory by redefining an ALF adaptation parameter set id still referenced by slices. Attackers can supply a crafted VVC bitstream that, with multithreaded decoding, makes worker threads dereference freed APS objects in CABACReader::readAlf() and AdaptiveLoopFilter::reconstructCoeff(), causing crashes or heap corruption.
CVE-2026-125269 1 Ffmpeg 1 Ffmpeg 2026-11-09 7 High
FFmpeg through 9.0.2 contains a double free vulnerability in libavcodec/cbs_sei.c where cbs_sei_delete_message() leaves a stale extension_data reference that ff_cbs_sei_add_message() reuses. Attackers can supply a crafted H.264 stream with a display orientation SEI message followed by payload extension data, processed by h264_metadata with display_orientation=insert, to corrupt heap memory.
CVE-2026-125265 1 Ffmpeg 1 Ffmpeg 2026-11-09 5.3 Medium
FFmpeg through 9.0.2 contains a use-after-free vulnerability in libavcodec/nvdec.c because ff_nvdec_start_frame() fails to reset ctx->bitstream after slice errors. Attackers can supply crafted video that abandons a picture before end_frame, causing cuvidDecodePicture() to read freed heap memory, crashing applications or exposing stale heap contents.
CVE-2026-125255 1 Ffmpeg 1 Ffmpeg 2026-11-09 5.3 Medium
FFmpeg through 9.0.2 contains a use after free vulnerability in libavcodec/mjpegdec.c that allows attackers to trigger freed buffer reads by sending a SOF marker without a preceding SOI. Attackers can supply crafted MJPEG streams causing ff_mjpeg_decode_sof() to pass a stale raw_image_buffer pointer to hwaccel decoders like NVDEC, crashing applications or leaking heap contents.
