CVE-2026-88964

A flaw was found in OpenVPN. An integer underflow vulnerability allows a remote authenticated server to trigger a Denial of Service DoS or disclose sensitive memory contents on connected client systems. By providing specially crafted domain search options, a malicious or compromised server can...

CVE-2026-73252

A flaw was found in Mongoose. An unauthenticated remote attacker can cause a Denial of Service DoS by sending a specially crafted Transport Layer Security TLS record to an affected server. Due to improper message length validation in the built-in TLS implementation, processing the malformed recor...

Astra Linux – Vulnerability in gnutls28

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

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323 – check for zero length in DecodeQ931. In DecodeQ931, the UserUserIE code path reads a 16-bit length from the packet, then decrements it by 1 to skip the protocol discriminator byte before passing it to...

Astra Linux – Vulnerability in xrdp

XRDPT is an open-source remote desktop protocol RDP server. In affected versions, an integer underflow leading to a heap overflow in the SESMAN server allows any unauthenticated attacker who can access the SESMAN server locally to execute code as root. This vulnerability has been patched in versi...

Astra Linux – Vulnerability in grub2

Integer underflow in grubnetrecvip4packets; A malicious IP packet can cause an integer underflow in the grubnetrecvip4packets function, affecting the rsm-totallen value. Under certain circumstances, the totallen value may wrap around to a small integer number, which will be used in memory...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: qat – added parameter checks for RSA. Requests with a source buffer size greater than the size of the key are rejected. This prevents potential integer underflow issues that might occur when copying the source scatterlist...

Astra Linux – Vulnerability in Qemu

QEMU prior to version 8.2.0 has an integer underflow issue, which can lead to a buffer overflow. This occurs due to a TI command, where a transfer length that is not a DMA transfer is processed, and the actual transfer length is shorter than the length of the available FIFO data. This issue arise...
