CVE-2026-54538 xrdp: Pre-auth infinite loop via totalLength=0 in TS_SHARECONTROLHEADER

xrdp is an open source RDP server. In versions 0.10.6 and prior, a n issue was discovered where the software fails to properly validate the totalLength field within the RDP protocol control header during packet reception. An unauthenticated remote attacker can exploit this vulnerability by sendin...

CVE-2026-54538

CVE-2026-54538 affects xrdp up to version 0.10.6, where the server fails to validate the totalLength field in the RDP protocol control header. An unauthenticated attacker can send a crafted packet that makes the xrdp process enter an infinite, CPU‑bound loop, due to a pointer not advancing and by...

EUVD-2026-46011

In the Linux kernel, the following vulnerability has been resolved: i2c: stub: Reject I2C block transfers with invalid length The I2CSMBUSI2CBLOCKDATA case in stubxfer uses data-block0 as the transfer length. The existing check only clamps it to avoid overrunning the chip-words256 register array,...

DEBIAN-CVE-2026-26199

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-2026-26199

The CVE-2026-26199 entry describes a buffer underflow in HDF5 when calling H5Iget_name (and H5G_get_name) with a size of zero. Under conditions where an ID is queried with size forced to zero and there is significant data before the name buffer, the function may fail to place a null terminator, l...

CVE-2026-53392

A flaw was found in the Linux kernel's NFSv4 Network File System version 4 flexfiles component. This vulnerability occurs when the fflayoutalloclseg function processes a malformed flexfiles layout that specifies a zero filehandle version count. An attacker could exploit this by providing a...

CVE-2026-53391

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...

CVE-2026-64159

A flaw was found in the Linux kernel's network file system netfs component. This vulnerability occurs when the local file size is larger than the size reported by the remote server, leading to an incorrect update of the 'zero point' a file position used to optimize reads. An attacker could...

CVE-2026-64048

A flaw was found in the Linux kernel's Server-Message-Block Direct SMC-D client. A remote attacker can exploit this vulnerability by sending a specially crafted SMC-Dv2 proposal with a Channel Identifier CHID of 0. This malicious proposal can cause a null pointer dereference in the kernel's SMC...

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...
