CVE-2026-48131 1 Checkpoint 1 Quantum Security Gateway 2026-05-26 8.1 High
The VPN service may mishandle an unexpected IKE fragment value received on the IKE port 500/UDP during the early stage of a connection attempt. This can cause the service to terminate unexpectedly, resulting in denial of service (temporary disruption of VPN-related functionality).
CVE-2026-43390 1 Linux 1 Linux Kernel 2026-05-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: nstree: tighten permission checks for listing Even privileged services should not necessarily be able to see other privileged service's namespaces so they can't leak information to each other. Use may_see_all_namespaces() helper that centralizes this policy until the nstree adapts.

CVE-2026-9365 1 Ettercap 1 Ettercap 2026-05-26 5.6 Medium
A vulnerability has been found in Ettercap up to 0.8.3. The affected element is the function FUNC_DECODER of the file src/dissectors/ec_gg.c of the component GG Dissector. The manipulation of the argument gg leads to heap-based buffer overflow. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is described as difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 0.8.4 is sufficient to fix this issue. The identifier of the patch is feeae6fa366e01a3dd9f1857ec6aae847b2ae00c. It is suggested to upgrade the affected component.
CVE-2026-9500 1 Gnu 1 Libredwg 2026-05-26 5.3 Medium
A vulnerability was found in GNU LibreDWG up to 0.14. The affected element is the function read_2004_compressed_section of the file src/decode.c of the component Dwgread Utility. Performing a manipulation results in heap-based buffer overflow. The attack is only possible with local access. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-9502 1 Gnu 1 Libredwg 2026-05-26 5.3 Medium
A vulnerability was identified in GNU LibreDWG up to 0.14. This affects the function decompress_R2004_section of the file src/decode.c of the component Dwgread Utility. The manipulation leads to heap-based buffer overflow. The attack must be carried out locally. The exploit is publicly available and might be used. The identifier of the patch is e501cb9926c1e9a07a0d1cc997f3e69e9be801c9. To fix this issue, it is recommended to deploy a patch.
CVE-2026-23750 1 Golioth 1 Pouch 2026-05-26 8.1 High
Golioth Pouch version 0.1.0, prior to commit 1b2219a1, contains a heap-based buffer overflow in BLE GATT server certificate handling. server_cert_write() allocates a heap buffer of size CONFIG_POUCH_SERVER_CERT_MAX_LEN when receiving the first fragment, then appends subsequent fragments using memcpy() without verifying that sufficient capacity remains. An adjacent BLE client can send unauthenticated fragments whose combined size exceeds the allocated buffer, causing a heap overflow and crash; integrity impact is also possible due to memory corruption.
CVE-2025-34523 1 Arcserve 1 Udp 2026-05-26 9.8 Critical
A heap-based buffer overflow vulnerability exists in the network-facing input handling routines of Arcserve Unified Data Protection (UDP). This flaw is reachable without authentication and results from improper bounds checking when processing attacker-controlled input. By sending specially crafted data, a remote attacker can corrupt heap memory, potentially causing a denial of service or enabling arbitrary code execution depending on the memory layout and exploitation techniques used. This vulnerability is similar in nature to CVE-2025-34522 but affects a separate code path or component. No user interaction is required, and exploitation occurs in the context of the vulnerable process. This vulnerability affects all UDP versions prior to 10.2. UDP 10.2 includes the necessary patches and requires no action. Versions 8.0 through 10.1 are supported and require either patch application or upgrade to 10.2. Versions 7.x and earlier are unsupported or out of maintenance and must be upgraded to 10.2 to remediate the issue.
CVE-2025-31201 1 Apple 5 Ipados, Iphone Os, Macos and 2 more 2026-05-25 9.8 Critical
This issue was addressed by removing the vulnerable code. This issue is fixed in iOS 18.4.1 and iPadOS 18.4.1, macOS Sequoia 15.4.1, tvOS 18.4.1, visionOS 2.4.1. An attacker with arbitrary read and write capability may be able to bypass Pointer Authentication. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on iOS.
CVE-2026-8997 1 Vifm 1 Vifm 2026-05-25 N/A
vifm is vulnerable to a heap buffer overflow during the history merge process when saving the state file (vifminfo.json). This flaw occurs because the application lacks a runtime check on the length of history entries in release builds, potentially allowing a crafted long path or command in the history to cause memory corruption or application crashes. Releases from 0.12.1 to 0.14.3 (including) are considered vulnerable. This issue was fixed in commit 23063c7
CVE-2026-42831 1 Microsoft 6 365 Copilot, Office, Office For Android and 3 more 2026-05-22 7.8 High
Heap-based buffer overflow in Microsoft Office allows an unauthorized attacker to execute code locally.
CVE-2026-40363 1 Microsoft 11 365 Apps, 365 Copilot, Office and 8 more 2026-05-22 8.4 High
Heap-based buffer overflow in Microsoft Office allows an unauthorized attacker to execute code locally.
CVE-2026-33633 1 Kovidgoyal 1 Kitty 2026-05-22 7.5 High
Kitty is a cross-platform GPU based terminal. Versions 0.46.2 and below contain a heap buffer overflow in load_image_data() that allows any process which can write to the terminal's stdin to crash kitty immediately. The vulnerability is triggered by a single APC graphics protocol command with a PNG format declaration (f=100) whose payload exceeds twice the initial buffer capacity. The overflow is attacker-controlled in both length and content, causing DoS and potentially escalation to RCE itself. This issue has been fixed in version 0.47.0.
