CVE-2025-5222 2 Redhat, Unicode 6 Enterprise Linux, Openshift, Rhel E4s and 3 more 2026-11-05 7 High
A stack buffer overflow was found in Internationl components for unicode (ICU ). While running the genrb binary, the 'subtag' struct overflowed at the SRBRoot::addTag function. This issue may lead to memory corruption and local arbitrary code execution.
CVE-2025-0689 2 Gnu, Redhat 4 Grub2, Enterprise Linux, Openshift and 1 more 2026-11-05 7.8 High
When reading data from disk, the grub's UDF filesystem module utilizes the user controlled data length metadata to allocate its internal buffers. In certain scenarios, while iterating through disk sectors, it assumes the read size from the disk is always smaller than the allocated buffer size which is not guaranteed. A crafted filesystem image may lead to a heap-based buffer overflow resulting in critical data to be corrupted, resulting in the risk of arbitrary code execution by-passing secure boot protections.

CVE-2026-80186 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-04 7.6 High
A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code execution.

CVE-2026-30871 1 Openwrt 1 Openwrt 2026-11-03 9.8 Critical
OpenWrt Project is a Linux operating system targeting embedded devices. In versions prior to 24.10.6 and 25.12.1, the mdns daemon has a Stack-based Buffer Overflow vulnerability in the parse_question function. The issue is triggered by PTR queries for reverse DNS domains (.in-addr.arpa and .ip6.arpa). DNS packets received on UDP port 5353 are expanded by dn_expand into an 8096-byte global buffer (name_buffer), which is then copied via an unbounded strcpy into a fixed 256-byte stack buffer when handling TYPE_PTR queries. The overflow is possible because dn_expand converts non-printable ASCII bytes (e.g., 0x01) into multi-character octal representations (e.g., \001), significantly inflating the expanded name beyond the stack buffer's capacity. A crafted DNS packet can exploit this expansion behavior to overflow the stack buffer, making the vulnerability reachable through normal multicast DNS packet processing. This issue has been fixed in versions 24.10.6 and 25.12.1.
CVE-2019-5439 1 Videolan 1 Vlc Media Player 2026-11-02 N/A
A Buffer Overflow in VLC Media Player < 3.0.7 causes a crash which can possibly be further developed into a remote code execution exploit.
CVE-2026-120226 1 Hangzhou Xiongmai Technology 1 P2papi.dll 2026-11-01 3.3 Low
A security vulnerability has been detected in Hangzhou Xiongmai Technology P2PAPI.dll 1.3.3.32 on Windows. Affected by this issue is the function P2PAPI_Connect of the component P2P SDK. Such manipulation of the argument input as part of String leads to buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-63899 1 Linux 1 Linux Kernel 2026-10-30 7.8 High
In the Linux kernel, the following vulnerability has been resolved: USB: serial: mxuport: fix memory corruption with small endpoint Make sure that the bulk-out endpoint max packet size is at least eight bytes to avoid user-controlled slab corruption should a malicious device report a smaller size.
CVE-2026-89652 1 Linux 1 Linux Kernel 2026-10-30 9.8 Critical
In the Linux kernel, the following vulnerability has been resolved: ceph: bound copied dentry name length in NFS export get_name ceph_get_name() copies the MDS-supplied name into the caller's NAME_MAX-sized buffer with memcpy(name, rinfo->dname, rinfo->dname_len) and then writes name[rinfo->dname_len] = 0, without checking dname_len against NAME_MAX. A malicious or buggy MDS that returns a LOOKUPNAME reply with dname_len > NAME_MAX overflows the buffer. __get_snap_name() copies rde->name / rde->name_len the same unchecked way. Impact: a malicious or compromised Ceph MDS overflows the NAME_MAX name buffer in a client's NFS-export get_name path, a slab out-of-bounds write reported by KASAN. Reachable when a CephFS mount is re-exported over NFS. Add ceph_export_copy_name(), which rejects lengths above NAME_MAX with -ENAMETOOLONG before the copy, and use it in both ceph_get_name() and __get_snap_name().
CVE-2026-80576 1 Linux 1 Linux Kernel 2026-10-30 8.8 High
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: reject oversized IBs with per-ring packet limits On GFX rings, amdgpu_cs_p2_ib() passed user-supplied ib_bytes through to ib->length_dw without a limit, while ring_emit_ib() encodes length into packet fields. Oversized values can corrupt adjacent control bits and destabilize command submission. Add a per-ring IB packet size limit helper and reject command submissions exceeding the corresponding dword limit before IB allocation. Use the documented 20-bit limit for GFX/compute/SDMA/VPE, and apply the MM fallback limit for other ring types. (cherry picked from commit 7f48fa2cf62e3fa6c9c3870aa74988f773247e52)
CVE-2026-74391 1 Linux 1 Linux Kernel 2026-10-30 7.0 High
In the Linux kernel, the following vulnerability has been resolved: tracing: Bound synthetic-field strings with seq_buf The synthetic field helpers build a prefixed synthetic variable name and a generated hist command in fixed MAX_FILTER_STR_VAL buffers. The current code appends those strings with raw strcat(), so long key lists, field names, or saved filters can run past the end of the staging buffers. Build both strings with seq_buf and propagate -E2BIG if either the synthetic variable name or the generated command exceeds MAX_FILTER_STR_VAL. This keeps the existing tracing-side limit while using the helper intended for bounded command construction. [ sdr: Moved struct seq_buf *s for upside-down x-mas tree formatting ]
CVE-2026-74341 1 Linux 1 Linux Kernel 2026-10-30 8.8 High
In the Linux kernel, the following vulnerability has been resolved: wifi: wcn36xx: fix heap overflow from oversized firmware HAL response The firmware response dispatcher copies all synchronous HAL responses into the 4096-byte hal_buf without validating the response length. A response exceeding WCN36XX_HAL_BUF_SIZE causes a heap buffer overflow with firmware-controlled content. Add a bounds check on the response length.
CVE-2026-68293 1 Linux 1 Linux Kernel 2026-10-30 7.1 High
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix MCIA register buffer overflow on 32 dword reads The MCIA register can return up to 32 dwords (128 bytes) when the device advertises the mcia_32dwords capability, but struct mlx5_ifc_mcia_reg_bits only defines dword_0..11, leaving room for just 12 dwords (48 bytes) of data. mlx5_query_mcia() clamps the read size to mlx5_mcia_max_bytes() and then memcpy()s that many bytes out of the register, potentially reading past the end of the 'out' buffer. On kernels built with FORTIFY_SOURCE this is caught as a buffer overflow while reading the module EEPROM via ethtool: detected buffer overflow in memcpy kernel BUG at lib/string_helpers.c:1048! RIP: 0010:fortify_panic+0x13/0x20 Call Trace: mlx5_query_mcia.isra.0+0x200/0x210 [mlx5_core] mlx5_query_module_eeprom_by_page+0x4a/0xa0 [mlx5_core] mlx5e_get_module_eeprom_by_page+0xbb/0x120 [mlx5_core] eeprom_prepare_data+0xf3/0x170 ethnl_default_doit+0xf1/0x3b0 Extend the mcia_reg layout to 32 dwords.
CVE-2020-37202 1 Nsasoft 2 Network Sleuth, Nsauditor Networksleuth 2026-10-27 7.5 High
NetworkSleuth 3.0.0.0 contains a denial of service vulnerability that allows attackers to crash the application by supplying an oversized registration key. Attackers can generate a 1000-character buffer payload and paste it into the registration key field to trigger an application crash.
CVE-2019-25733 1 Nsasoft 2 Netsharewatcher, Nsauditor Netsharewatcher 2026-10-27 8.4 High
NetShareWatcher 1.5.8.0 contains a structured exception handler buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying malicious input. Attackers can craft a payload with overwritten SEH and NSEH pointers through the Restrictions custom filter field to trigger code execution when the Find function is invoked.
