CVE-2026-6103 2 Php Group, Redhat 2 Php, Hummingbird 2026-09-26 4.3 Medium
phar_tar_number() parses the octal size field of a TAR header into a uint32_t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlled file content as the next TAR header, which lets a crafted archive inject entries that PharData reports and extracts as if they were genuine.
CVE-2025-14181 1 Php Group 1 Php 2026-09-26 6.5 Medium
The SOAP HTTP client guards its response buffer growth with a check that relies on signed integer overflow, which is undefined behaviour and is not guaranteed to trigger. When the check is optimised away, a malicious SOAP server can make the client allocate a buffer far smaller than the data it then writes into it, producing a heap buffer overflow.
CVE-2026-88412 2026-09-26 5.3 Medium
An integer overflow in the _BulkInsert_ReadProperty component (/bulk_insert.c) of FalkorDB (Redis module) v4.20.1 allows attackers to cause a Denial of Service (DoS) via a crafted input.
CVE-2026-88351 1 Ludocode 1 Mpack 2026-09-26 9.8 Critical
An integer overflow vulnerability exists in the MPack Node API in MPack 1.1.1 on 32-bit platforms. When parsing a specially crafted MessagePack array32 or map32 object with an excessively large element count, the page allocation size calculation in mpack_tree_parse_children() can overflow size_t and produce an undersized allocation. Subsequent parsing writes mpack_node_data_t records beyond the allocated heap buffer, resulting in heap-buffer-overflow, memory corruption, and denial of service.
CVE-2026-88365 2026-09-26 N/A
minimp3 commit ea99364f contains an integer overflow vulnerability in mp3dec_skip_id3v1() when parsing the APEv2 tag-size field.
CVE-2026-88376 2026-09-26 7.5 High
Bento4 1.6.0.0 contains an integer underflow vulnerability in AP4_AvccAtom::Create() and AP4_HvccAtom::Create(). A specially crafted MP4 file containing an avcC or hvcC atom with a declared size smaller than the atom header size can cause the payload-size calculation to wrap to a large unsigned value. The resulting invalid buffer allocation and copy operations can cause application termination, leading to denial of service.
CVE-2026-88377 2026-09-26 N/A
Bento4 1.6.0.0 contains an integer underflow vulnerability in the avcC and hvcC configuration atom parsers. A specially crafted MP4 file containing an atom with a declared size smaller than AP4_ATOM_HEADER_SIZE can cause AP4_AvccAtom::Create() or AP4_HvccAtom::Create() to underflow the payload-size calculation. The resulting oversized buffer operation can cause invalid or NULL pointers to be passed to the AP4_DataBuffer copy path, resulting in application termination and denial of service.
CVE-2026-97451 1 Linux 1 Linux Kernel 2026-09-26 8.4 High
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op) Add overflow check for Index + Length to prevent integer overflow when calculating the truncation length. This prevents negative size parameter being passed to memcpy().
CVE-2026-93227 1 Linux 1 Linux Kernel 2026-09-26 N/A
In the Linux kernel, the following vulnerability has been resolved: mm/mm_init: deferred_grow_zone(): fix out-of-range first_deferred_pfn With CONFIG_DEFERRED_STRUCT_PAGE_INIT enabled, deferred_grow_zone() initializes struct pages early in boot to satisfy an allocation. With a large CMA reservation in place, the ranges deferred_init_memmap() finds may not add up to the allocation it was asked for, and the function ends up initializing the memory map of the entire zone and still falls short. That is fine in itself: the function accounts for it and leaves the caller to decide whether it now has enough memory. However, the update of pgdat->first_deferred_pfn that tracks where uninitialized memory map starts could overflow. If the node's RAM end is not aligned on PAGES_PER_SECTION boundaries and some deferred struct pages were initialized, pgdat->first_deferred_pfn would point past the end of the node's memory. deferred_init_memmap() later picks up from pgdat->first_deferred_pfn and hits a BUG_ON(), because it expects a pfn within its node. For example, when running a kernel with CONFIG_DEFERRED_STRUCT_PAGE_INIT=y and CONFIG_CMA=y using the following qemu command line qemu-system-x86_64 -enable-kvm -m 8032M -kernel bzImage \ -append "nokaslr cma=4768M@0x100000000" the kernel panics: kernel BUG at mm/mm_init.c:2131!

CVE-2026-83601 1 Netdata 1 Netdata 2026-09-26 6.5 Medium
Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized DIMENSION SLOT value that str2ull_encoded passes to pluginsd_rrddim_put_to_slot in src/plugins.d/pluginsd_internals.h without an upper bound. prd_array_create in src/database/rrdset-pluginsd-array.h can then wrap the size_t allocation calculation while retaining the original large array size, causing the subsequent initialization loop to write beyond the undersized heap allocation and crash the parent agent. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.
CVE-2026-97523 1 Linux 1 Linux Kernel 2026-09-25 7.5 High
In the Linux kernel, the following vulnerability has been resolved: mptcp: close race between scheduler and state change The mptcp scheduler may race with subflow sockets state change: data transmission on the selected socket may fail and a later release could try to use mss_now reset to 0 for a divide operation. Address the issue by explicitly checking for the critical scenario.
CVE-2026-98002 1 Linux 1 Linux Kernel 2026-09-25 7.8 High
In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Fix ineffective error check in nested domain allocation amd_iommu_pdom_id_alloc() returns an int: a domain ID on success, or the negative errno from ida_alloc_range() when the ID space is exhausted or memory is short. amd_iommu_alloc_domain_nested() stores that return value in gdom_info->hdom_id, which is a u32, and only then tests it: gdom_info->hdom_id = amd_iommu_pdom_id_alloc(); if (gdom_info->hdom_id <= 0) { The assignment discards the sign, so -ENOSPC becomes 0xffffffe4 and the test never fires. The nested domain is then set up with a host domain ID that was never allocated, instead of the allocation failing with -ENOSPC. Keep the value in an int, test it there, and store it only once it is known to be valid, which is what the other amd_iommu_pdom_id_alloc() callers already do.
CVE-2026-97551 1 Linux 1 Linux Kernel 2026-09-25 N/A
In the Linux kernel, the following vulnerability has been resolved: xfs: initialise args->total for parent pointer updates xfs_parent_da_args_init() builds an xfs_da_args from a zeroed xfs_parent_args (kmem_cache_zalloc), leaving args->total == 0. xfs_da_grow_inode_int() treats that field as a running block reservation and subtracts from it; because it is an xfs_extlen_t (uint32_t), the first attr-fork growth wraps it to ~0U. That defeats the free-space check in xfs_alloc_space_available(), and when it coincides with an AG that has exactly zero available blocks the allocation is clamped to maxlen 0 and returns -ENOSPC, which xfs_defer_finish_noroll() escalates to a filesystem shutdown. Set args->total the way the log recovery path does (xfs_attri_recover_work(), xfs_attr_item.c:706), in the add and replace paths that can grow the fork. Removals and lookups never grow it, so they leave the field alone, matching that switch.
CVE-2026-97613 1 Linux 1 Linux Kernel 2026-09-25 N/A
In the Linux kernel, the following vulnerability has been resolved: net: mana: Reserve extra CQ slot for the fence completion CQE The RX completion queue is sized to hold exactly one CQE per posted RX WQE. MANA_FENCE_RQ makes hardware post an additional CQE_RX_OBJECT_FENCE after the packet CQEs. The current sizing reserves no extra slot for it and in rare cases, CQ has no guaranteed slot for the fence CQE when it is full of packet CQEs. This can lead to dropping the fence completion while the driver waits holding RTNL lock throughout the timeout duration. Reserve one extra CQE slot for CQE_RX_OBJECT_FENCE. mana_gd_alloc_memory() requires queue_size to be a power-of-two and at least MANA_PAGE_SIZE; the reservation pushes cq_size past a power-of-two, so round up the CQ size in mana_create_rxq().
CVE-2026-98051 1 Linux 1 Linux Kernel 2026-09-25 N/A
In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix tx_spb_ring_full() checking same slot cnt times The loop initialised next_index from intf->tx_spb_index on every iteration, so incr_ring() always produced the same result and only one slot was ever tested. Move the initialisation before the loop so each iteration advances next_index and the function correctly checks that cnt consecutive descriptor slots are available before allowing a new transmission.
CVE-2026-10758 2026-09-25 7.5 High
Esri LERC is an open-source image or raster format which supports rapid encoding and decoding for any pixel type. A Heap based Out-of-Bounds Write via Integer Overflow in LERC versions 4.1.0 and earlier may allow a remote, unauthenticated attacker who can pass specifically crafted attacker controlled imagery to an application that uses LERC to crash the application, leading to a denial of service.
CVE-2026-93395 1 Mongodb 1 C Driver 2026-09-25 5.3 Medium
A missing lower-bound validation in the bson_new_from_buffer() function of libbson allows an integer underflow when processing BSON data with a zero-length prefix. The function reads a 32-bit document length from the input buffer but does not verify that the value is at least 5 (the minimum valid BSON document size) before using it in an array index calculation. When the length field is zero, the expression used to check the document's null terminator wraps to UINT32_MAX, causing a heap out-of-bounds read that crashes the process. An unauthorized party who can supply crafted BSON input to an application using this API can cause a denial of service.
CVE-2026-100208 1 Microsoft 3 365 Apps, Office 2021, Office 2024 2026-09-25 7.5 High
Integer overflow or wraparound in Microsoft Office Outlook allows an unauthorized attacker to execute code over a network.
CVE-2026-62699 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-25 6.8 Medium
Null pointer dereference in Windows Universal Disk Format File System Driver (UDFS) allows an authorized attacker to execute code locally.
CVE-2026-97954 1 Linux 1 Linux Kernel 2026-09-25 N/A
In the Linux kernel, the following vulnerability has been resolved: net/rds: fix tcp stream corruption with large pages rds_message_map_pages() assigns PAGE_SIZE bytes to every scatterlist entry, even when total_len ends in a partial page. The RDS congestion map is defined as 8192 bytes, so on systems with PAGE_SIZE greater than 8192 the scatterlist maps bytes beyond the end of the congestion map. RDS-TCP transmits the SG contents according to those lengths, so the extra bytes become part of the TCP RDS stream and are interpreted as subsequent RDS message headers, corrupting the stream. Limit the final scatterlist mapping to the number of bytes remaining. This has no effect on systems with a 4K page size and allows RDS-TCP to be used on systems with 16K and larger page sizes. The RDS selftest, which previously hung on 16K pages, now passes.
