CVE-2026-26199 Buffer underflow in `H5Iget_name `/`H5G_get_name` if size is zero

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If H5Igetname is invoked on a group id with 0 for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if H5Igetname is invoked in a way...

CVE-2026-53994

A flaw was found in ProFTPD's modsftp module. An authenticated SFTP user can exploit a heap-based buffer overflow by sending a specially crafted SFTP packet with a zero-length value. This can lead to an unsigned integer underflow, causing the system to allocate a small memory block while expectin...

gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...

Medium: krb5

Issue Overview: An integer underflow vulnerability was found in MIT krb5 in the berval2tldata function in plugins/kdb/ldap/libkdbldap/ldapprincipal2.c. The function performs an unsigned subtraction bvlen - 2 without a prior bounds check. When bvlen is 0 or 1, the subtraction wraps to a large valu...
