CVE-2026-107614

GlavSoft TightVNC Server for Windows versions before 2.8.88 are vulnerable to an integer underflow in the WinCursorShapeUtils::trimTransparent() function. When a cursor shape with a width or height of zero is processed on the DXGI capture path , the loop bound width - 1 wraps to 0xFFFFFFFF. This ...

EUVD-2026-94978

An integer underflow in WinCursorShapeUtils::trimTransparent in GlavSoft TightVNC Server for Windows before 2.8.88 allows a local authenticated user to crash the server, and potentially read out-of-bounds memory, by causing a cursor shape with a width or height of zero to be processed on the DXGI...

CVE-2026-98176

A flaw was found in the Linux kernel's AMD GPU driver amdkfd. An integer underflow vulnerability during the calculation of the End of Pipe EOP ring buffer size can lead to improper hardware queue configuration. A local user could potentially exploit this issue to cause system instability, resulti...

kernel: RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv

A flaw was found in the Linux kernel's RDMA/rxe component. The rxercv function does not adequately validate the BTH pad and ICRC fields of incoming packets before calculating the payload size. A remote attacker could exploit this by sending a specially crafted short packet or a packet with a forg...

CVE-2026-107635: Integer Underflow (Wrap or Wraparound)

Dislocker through 0.7.3 contains an integer underflow vulnerability in getvmk and getfvek that allows attackers to trigger out-of-bounds heap reads via crafted datum sizes. Attackers can supply a malicious BitLocker volume image with a datumsize smaller than the 36-byte AES-CCM header, causing...

CVE-2026-106437: Integer Underflow (Wrap or Wraparound)

The BSON buffer-reservation API in the MongoDB C Driver can record a length smaller than the five-byte BSON minimum. Later append or comparison operations can underflow unsigned length calculations and read or write outside the document buffer. An actor who can influence the length supplied by an...

Name of the Vulnerable Software and Affected Versions SumatraPDF versions prior to 3.6.2 Description The ChmFile::GetCharZ function narrows file-controlled unsigned string offsets from /WINDOWS and /IVB to signed integers without performing a lower-bound check. If an offset becomes negative, the...

EulerOS 2.0 SP15 : graphite2 (EulerOS-SA-2026-3978)

According to the versions of the graphite2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : Graphite before 1.3.15 has an integer underflow and resultant out-of-bounds write via Graphite actions, because slotat does not ensure that an...

PT-2026-107994

Name of the Vulnerable Software and Affected Versions Dislocker versions prior to 0.7.4 Description An integer underflow exists in the get vmk and get fvek functions. This issue allows attackers to trigger out-of-bounds heap reads by providing a malicious BitLocker volume image where the datum si...

PT-2026-108135

Name of the Vulnerable Software and Affected Versions MongoDB libmongocrypt affected versions not specified Description An integer underflow exists in the KMS endpoint-parsing logic. This occurs when an authenticated user modifies a key document in the key vault collection, or when an application...

CVE-2026-106429: Integer Underflow (Wrap or Wraparound)

An integer underflow in the KMS endpoint-parsing logic of MongoDB libmongocrypt can cause an allocation failure that terminates the application process. This can occur when an authenticated user modifies a key document in the key vault collection, or when an application accepts a KMS endpoint...

CVE-2026-107614: Integer Underflow (Wrap or Wraparound)

An integer underflow in WinCursorShapeUtils::trimTransparent in GlavSoft TightVNC Server for Windows before 2.8.88 allows a local authenticated user to crash the server, and potentially read out-of-bounds memory, by causing a cursor shape with a width or height of zero to be processed on the DXGI...

popt-devel: popt-static: size_t underflow in singleOptionHelp

An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of servi...

CVE-2026-19186 Integer underflow in IEEE 802.15.4 frame decryption leads to out-of-bounds read and write

ieee802154decipherdataframe in subsys/net/l2/ieee802154/ieee802154frame.c computed payloadlen = netpktgetlenpkt - llhdrlen - authtaglen without first checking that the received frame is at least llhdrlen + authtaglen bytes long. All three variables are uint8t, so a frame whose payload is shorter...
