CVE-2026-6682

CVE-2026-6682 affects FatFs in R0.16 and earlier, where in mount_volume() a multiply operation fasize *= fs->n_fats can overflow, causing an integer wrap. This overflow can lead to attacker-controlled file-size metadata and unsafe read lengths in downstream callers. Impact described as CWE-190...

SUSE CVE-2026-53238

In the Linux kernel, the following vulnerability has been resolved: netlabel: validate unlabeled address and mask attribute lengths netlblunlabeladdrinfoget used the address attribute length to determine whether the attribute data could be read as an IPv4 or IPv6 address, but did not independentl...

CVE-2026-53224

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. Specifically, improper validation of embedded INIT chunk and address list lengths in SCTP cookies could allow a remote attacker to trigger out-of-bounds reads. This could lead to information disclosur...

Astra Linux – Vulnerability in glib2.0

A flaw was discovered in Glib’s content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored as a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access...

ROS-20260624-73-0013

The vulnerability in Python-Django is related to errors in processing parameter lengths of input data. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

CVE-2026-48510 MessagePack-CSharp: LZ4 decompression allocates from unbounded declared output lengths

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, when MessagePack-CSharp decompresses Lz4Block or Lz4BlockArray payloads, it reads declared uncompressed lengths from the wire and allocates output buffers based on those lengths before validating that the compressed...

CVE-2026-48515

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, MessagePack-CSharp's multi-dimensional array formatters read dimension lengths directly from the payload and allocate T,, T,,, or T,,, before validating that the dimension product matches the encoded element count. T...

GHSA-JM82-FX9C-MX94 pypdf: Missing stream length values ignore defined limits

Impact An attacker who uses this vulnerability can craft a PDF which leads to large memory usage, as MAXDECLAREDSTREAMLENGTH is sometimes ignored. This requires parsing a content stream without a /Length value. Patches This has been fixed in pypdf==6.13.3. Workarounds If you cannot upgrade yet,...

CVE-2026-48979

The CVE concerns PHP PSL versions 6.1.0, 6.1.1, and 6.2.0 where Psl\H2\ServerConnection fails to validate that the DATA frame length matches the content-length declared in the HEADERS frame, enabling HTTP request smuggling. This affects clients using Psl\H2\ServerConnection directly to process un...

GHSA-CH3Q-CW5R-F4HG ConnectBot SSH Client Library: Unbounded SSH field lengths can cause excessive memory allocation

Summary The SSH protocol parser trusted attacker-controlled length and count fields without first checking that the declared values fit within the containing packet. When a client connects to a malicious or compromised SSH server, the server can send a small, malformed packet containing an inner...
