CVE-2026-43006

A flaw was found in the Linux kernel's iouring subsystem. A local attacker can exploit a vulnerability in the ioimportfixed function by importing a zero-length fixed buffer. This can lead to an out-of-bounds read from slab memory, potentially resulting in information disclosure or a denial of...

CVE-2026-43006

In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: reject zero-length fixed buffer import validatefixedrange admits bufaddr at the exact end of the registered region when len is zero, because the check uses strict greater-than bufend imu-ubuf + imu-len. ioimportfixe...

CVE-2026-43006

CVE-2026-43006 (Linux kernel io_uring rsr/rsrc): A zero-length fixed-buffer import in io_import_fixed() could trigger a slab-out-of-bounds read due to a boundary check that allows len == 0 to be processed. The underlying issue is in validate_fixed_range(), which permits buf_addr at the end of the...

PT-2026-36423

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the io uring subsystem where the validate fixed range function allows a buffer address at the exact end of a registered region when the length is zero. This occurs...

CVE-2026-31531

A flaw was found in the Linux kernel. A local user can trigger a denial of service by querying a nexthop object with a large number of nexthop groups. This occurs because the kernel uses a fixed-size buffer that cannot accommodate the large response, leading to a kernel warning and potential syst...

Swift Crypto: X-Wing HPKE Decapsulation Accepts Malformed Ciphertext Length

Summary The X-Wing decapsulation path accepts attacker-controlled encapsulated ciphertext bytes without enforcing the required fixed ciphertext length. The decapsulation call is forwarded into a C API, which expects a compile-time fixed-size ciphertext buffer of 1120 bytes. This creates an FFI...

EUVD-2026-16903

The eswifi socket offload driver copies user-provided payloads into a fixed buffer without checking available space; oversized sends overflow eswifi-buf, corrupting kernel memory CWE-120. Exploit requires local code that can call the socket send API; no remote attacker can reach it directly...

CVE-2026-30929

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, MagnifyImage uses a fixed-size stack buffer. When using a specific image it is possible to overflow this buffer and corrupt the stack. This vulnerability is fix...

CVE-2025-70083

An issue was discovered in OpenSatKit 2.2.1. The DirName field in the telecommand is provided by the ground segment and must be treated as untrusted input. The program copies DirName into the local buffer DirWithSep using strcpy. The size of this buffer is OSMAXPATHLEN. If the length of DirName i...

PT-2026-2909

TinyOS versions up to and including 2.1.2 contain a global buffer overflow vulnerability in the printfUART formatted output implementation used within the ZigBee / IEEE 802.15.4 networking stack. The implementation formats output into a fixed-size global buffer and concatenates strings for %s...

CVE-2026-22184

zlib versions up to and including 1.3.1.2 include a global buffer overflow in the untgz utility located under contrib/untgz. The vulnerability is limited to the standalone demonstration utility and does not affect the core zlib compression library. The flaw occurs when a user executes the untgz...

CVE-2025-11782

CVE-2025-11782 affects Circutor SGE-PLC1000/SGE-PLC50 (v9.0.2). The ShowDownload() function uses sprintf() to format a string with user-controlled GetParameter(meter) input into a fixed 64-byte buffer (acStack_4c) without length checks, enabling a stack-based overflow if meter exceeds the buffer....
