CVE-2026-121517 1 Irfanview 1 Irfanview 2026-11-07 5 Medium
A vulnerability was detected in IrfanView 4.76.0.0 on Win64. Affected by this vulnerability is an unknown functionality of the component TIFF Wang Annotation Handler. Performing a manipulation results in heap-based buffer overflow. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit is now public and may be used. It is recommended to apply a patch to fix this issue. The vendor confirms: "[T]he TIF-Annotations option is OFF by default. Means, normal users are not affected ... the danger level for this is low".
CVE-2026-77709 1 Sonicwall 1 Sonicos 2026-11-06 5.9 Medium
A pre-authentication heap-based buffer overflow vulnerability has been identified in the SonicOS TACACS+ authentication client, which in specific conditions could potentially enable a remote unauthenticated attacker to cause an application level denial of service.

CVE-2026-121602 1 Solanum-ircd 1 Solanum 2026-11-06 6.5 Medium
Solanum before commit 2ce64de contains a heap-based buffer overflow vulnerability that allows a malicious linked server to corrupt memory by sending overlong channel names in JOIN or SJOIN messages. Attackers controlling a peer server can trigger strcpy and sprintf overflows in ms_join and ms_sjoin to crash the ircd or potentially achieve remote code execution.
CVE-2026-121941 1 Munt 1 Libmt32emu 2026-11-06 7.8 High
libmt32emu before 2.8.4 contains a heap buffer overflow vulnerability in MidiStreamParserImpl::parseSysex that allows attackers to write past a heap allocation by supplying oversized unterminated SysEx messages. Attackers can feed more than 32768 SysEx data bytes through the mt32emu_parse_stream API via MIDI files, ports, or sequencer clients to corrupt heap memory and crash the application.
CVE-2026-58953 1 Google 1 Android 2026-11-06 5.3 Medium
In dec_vlc_read of oapv_vlc.c, there is a possible out-of-bounds read due to a heap buffer overflow. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
CVE-2026-120775 1 Tanium 1 Deploy 2026-11-06 7.2 High
Tanium addressed a heap-based buffer overflow vulnerability in Deploy.
CVE-2026-120431 1 Netpbm Project 1 Netpbm 2026-11-06 7.8 High
Netpbm before 10.86.51, 11.x before 11.02.29, and 11.03 before 11.15.07 contains a heap-based buffer overflow in sgitopnm's readChannels() function when processing RLE-compressed SGI images. Attackers can supply crafted SGI files with oversized offset table lengths to write controlled data past the heap buffer, causing crashes or potential code execution.
CVE-2026-93536 1 X.org 3 X Server, Xorg-x11-server, Xwayland 2026-11-06 5.3 Medium
A use after free caused by missing lifecycle management of gesture sprites in GestureBuildSprite() in X.Org X Server before 21.1.25 and XWayland before 24.1.14 could be used by authenticated X clients to crash the X server or potentially execute code.
CVE-2026-114549 1 Nomachine 1 Nomachine 2026-11-06 N/A
NoMachine nxwebrunner Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NoMachine. Authentication is not required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 4443 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-30685.
CVE-2025-5915 2 Libarchive, Redhat 6 Libarchive, Enterprise Linux, Openshift and 3 more 2026-11-06 6.6 Medium
A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window. This means the library may attempt to read beyond the allocated memory buffer, which can result in unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information from adjacent memory regions.
CVE-2026-11792 1 Redhat 4 Directory Server, Enterprise Linux, Redhat Directory Server and 1 more 2026-11-06 3.3 Low
A heap buffer overflow flaw was found in 389 Directory Server. When audit logging is enabled, the create_masked_entry_string() function in auditlog.c copies a fixed-length password mask into a precisely-sized heap buffer without checking available space. If a short cleartext password is logged (requiring non-default CLEAR password storage or a compromised replication peer), the copy overflows the buffer, corrupting heap memory and audit log output.
CVE-2026-80757 1 Linux 1 Linux Kernel 2026-11-06 N/A
In the Linux kernel, the following vulnerability has been resolved: selinux: reject a class permission count below its inherited common security_get_permissions() maps an inherited common's permissions into an array sized by the class's own permissions.nprim, but class_read() takes that nprim verbatim from the policy image and never checks that it covers the common. A class that inherits a common of N permissions while declaring a smaller nprim is accepted, and on load the common's permissions are written past the class-sized array -- an out-of-bounds heap write. Reject a class whose permission count is below its inherited common's. Well-formed policies, where the class count already includes the inherited permissions, are unaffected.
CVE-2026-74676 1 Linux 1 Linux Kernel 2026-11-06 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: vt: add permission check for KDSKBMETA ioctl KDSKBMETA modifies keyboard meta mode but lacks the !perm check that all other keyboard setter ioctls in vt_k_ioctl() enforce, allowing a process to change meta mode on a non-controlling console without authorization.
CVE-2026-58835 1 Google 1 Android 2026-11-06 8.8 High
In cfg2prop of btif_storage.cc, there is a possible out-of-bounds write due to a heap buffer overflow. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.
CVE-2026-54914 1 Bytecodealliance 1 Wasm-micro-runtime 2026-11-06 N/A
WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime. Prior to 2.4.5, wasi_poll_oneoff in core/iwasm/libraries/libc-wasi/libc_wasi_wrapper.c validates the output pointer for only one wasi_event_t, while wasmtime_ssp_poll_oneoff in core/iwasm/libraries/libc-wasi/sandboxed-system-primitives/src/posix.c can write as many events as the guest-controlled nsubscriptions value. A crafted guest module can provide multiple subscriptions that produce events while positioning an output region large enough for only one event, causing a later out[nevents] write to cross the validated Wasm linear-memory boundary into adjacent host heap memory. The overwrite contains partly attacker-controlled event data and can reliably crash the host process, with further confidentiality or integrity consequences depending on heap layout. This issue is fixed in version 2.4.5.
CVE-2026-0100 1 Google 1 Android 2026-11-06 7.8 High
In Load of LoadedArsc.cpp, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
CVE-2026-112109 1 Thalesgroup 2 Safenet Authentication Client Service, Safenet Authentication Service 2026-11-06 7 High
A local privilege escalation vulnerability in Thales SafeNet Authentication Client (SAC) SACSrv can allow an authenticated, non-administrator local user to trigger a heap-based buffer overflow through the service interface. Successful exploitation may allow arbitrary code execution with Local System privileges.This issue affects SAC releases up to and including 10.9 R3 GA (build 10.9.7449).
