CVE-2026-21413	Cri	0.64	9.8	0.00	Apr 7, 2026	A heap-based buffer overflow vulnerability exists in the lossless_jpeg_load_raw functionality of LibRaw Commit 0b56545 and Commit d20315b. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2025-0657	Hig	0.57	—	0.00	Nov 27, 2025	A weakness in Automated Logic and Carrier i-Vu Gen5 router on driver version drv_gen5_106-01-2380, allows malformed packets to be sent through BACnet MS/TP network causing the devices to enter a fault state. This fault state requires a manual power cycle to return the device to network visibility.
CVE-2025-66559	Hig	0.52	—	0.00	Dec 4, 2025	Taiko Alethia is an Ethereum-equivalent, permissionless, based rollup designed to scale Ethereum without compromising its fundamental properties. In 2.3.1 and earlier, TaikoInbox._verifyBatches (packages/protocol/contracts/layer1/based/TaikoInbox.sol:627-678) advanced the local tid to whatever transition matched the current blockHash before knowing whether that batch would actually be verified. When the loop later broke (e.g., cooldown window not yet passed or transition invalidated), the function still wrote that newer tid into batches[lastVerifiedBatchId].verifiedTransitionId after decrementing batchId. Result: the last verified batch could end up pointing at a transition index from the next batch (often zeroed), corrupting the verified chain pointer.
CVE-2026-23447	Hig	0.51	7.8	0.00	Apr 3, 2026	In the Linux kernel, the following vulnerability has been resolved: net: usb: cdc_ncm: add ndpoffset to NDP32 nframes bounds check The same bounds-check bug fixed for NDP16 in the previous patch also exists in cdc_ncm_rx_verify_ndp32(). The DPE array size is validated against the total skb length without accounting for ndpoffset, allowing out-of-bounds reads when the NDP32 is placed near the end of the NTB. Add ndpoffset to the nframes bounds check and use struct_size_t() to express the NDP-plus-DPE-array size more clearly. Compile-tested only.
CVE-2026-23354	Hig	0.51	7.8	0.00	Mar 25, 2026	In the Linux kernel, the following vulnerability has been resolved: x86/fred: Correct speculative safety in fred_extint() array_index_nospec() is no use if the result gets spilled to the stack, as it makes the believed safe-under-speculation value subject to memory predictions. For all practical purposes, this means array_index_nospec() must be used in the expression that accesses the array. As the code currently stands, it's the wrong side of irqentry_enter(), and 'index' is put into %ebp across the function call. Remove the index variable and reposition array_index_nospec(), so it's calculated immediately before the array access.
CVE-2024-46871	Hig	0.51	7.8	0.00	Oct 9, 2024	In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Correct the defined value for AMDGPU_DMUB_NOTIFICATION_MAX [Why & How] It actually exposes '6' types in enum dmub_notification_type. Not 5. Using smaller number to create array dmub_callback & dmub_thread_offload has potential to access item out of array bound. Fix it.
CVE-2024-46859	Hig	0.51	7.8	0.00	Sep 27, 2024	In the Linux kernel, the following vulnerability has been resolved: platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses The panasonic laptop code in various places uses the SINF array with index values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array is big enough. Not all panasonic laptops have this many SINF array entries, for example the Toughbook CF-18 model only has 10 SINF array entries. So it only supports the AC+DC brightness entries and mute. Check that the SINF array has a minimum size which covers all AC+DC brightness entries and refuse to load if the SINF array is smaller. For higher SINF indexes hide the sysfs attributes when the SINF array does not contain an entry for that attribute, avoiding show()/store() accessing the array out of bounds and add bounds checking to the probe() and resume() code accessing these.
CVE-2024-46821	Hig	0.51	7.8	0.00	Sep 27, 2024	In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: Fix negative array index read Avoid using the negative values for clk_idex as an index into an array pptable->DpmDescriptor. V2: fix clk_index return check (Tim Huang)
CVE-2024-46813	Hig	0.51	7.8	0.00	Sep 27, 2024	In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check link_index before accessing dc->links[] [WHY & HOW] dc->links[] has max size of MAX_LINKS and NULL is return when trying to access with out-of-bound index. This fixes 3 OVERRUN and 1 RESOURCE_LEAK issues reported by Coverity.
CVE-2026-40886	Hig	0.50	7.7	0.00	Apr 23, 2026	Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. From 3.6.5 to 4.0.4, an unchecked array index in the pod informer's podGCFromPod() function causes a controller-wide panic when a workflow pod carries a malformed workflows.argoproj.io/pod-gc-strategy annotation. Because the panic occurs inside an informer goroutine (outside the controller's recover() scope), it crashes the entire controller process. The poisoned pod persists across restarts, causing a crash loop that halts all workflow processing until the pod is manually deleted. This vulnerability is fixed in 4.0.5 and 3.7.14.
CVE-2024-21522	Hig	0.49	7.5	0.00	Jul 10, 2024	All versions of the package audify are vulnerable to Improper Validation of Array Index when frameSize is provided to the new OpusDecoder().decode or new OpusDecoder().decodeFloat functions it is not checked for negative values. This can lead to a process crash.
CVE-2025-23278	Hig	0.46	7.1	0.00	Aug 2, 2025	NVIDIA Display Driver for Windows and Linux contains a vulnerability where an attacker might cause an improper index validation by issuing a call with crafted parameters. A successful exploit of this vulnerability might lead to data tampering or denial of service.
CVE-2023-51455	Med	0.44	6.8	0.00	Apr 2, 2024	A Improper Validation of Array Index issue affecting the v2_sdk_service running on a set of DJI drone devices on the port 10000 could allow an attacker to corrupt a controlled memory location due to a missing input validation in the on_receive_session_packet_ack function implemented in the libv2_sdk.so library used by the dji_vtwo_sdk binary implementing the service, potentially leading to a memory information leak or to an arbitrary code execution. Affected models are Mavic 3 Pro until v01.01.0300, Mavic 3 until v01.00.1200, Mavic 3 Classic until v01.00.0500, Mavic 3 Enterprise until v07.01.10.03, Matrice 300 until v57.00.01.00, Matrice M30 until v07.01.0022 and Mini 3 Pro until v01.00.0620.
CVE-2026-34942	Med	0.42	6.5	0.00	Apr 9, 2026	Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime's implementation of transcoding strings into the Component Model's utf16 or latin1+utf16 encodings improperly verified the alignment of reallocated strings. This meant that unaligned pointers could be passed to the host for transcoding which would trigger a host panic. This panic is possible to trigger from malicious guests which transfer very specific strings across components with specific addresses. Host panics are considered a DoS vector in Wasmtime as the panic conditions are controlled by the guest in this situation. This vulnerability is fixed in 24.0.7, 36.0.7, 42.0.2, and 43.0.1.
CVE-2026-32285	Hig	0.42	7.5	0.00	Mar 26, 2026	The Delete function fails to properly validate offsets when processing malformed JSON input. This can lead to a negative slice index and a runtime panic, allowing a denial of service attack.
