CVE-2026-34180

Issue summary: Parsing a crafted DER-encoded ASN.1 structure with a primitive element whose content exceeds 2 gigabytes in length may cause a heap buffer over-read on 64-bit Unix and Unix-like platforms. Impact summary: The heap buffer over-read may crash the application Denial of Service or to...

PT-2026-48154

The utility functions used by Malwarebytes EDR 1.0.11 on Linux for calculating a cryptographic hash of data bytes truncate the hashed data if it exceeds 4GB. This leads to an integer wrap-around if the data is larger than the maximum unsigned integer value 32-bit. Attackers could create a collidi...

CVE-2023-29146

CVE-2023-29146 affects Malwarebytes EDR 1.0.11 on Linux. The vulnerability lies in the utility functions that compute a cryptographic hash of data bytes: hashing truncates data if it exceeds 4 GB, causing an unsigned 32-bit wrap-around. This can enable attackers to craft a colliding hash value fo...

CVE-2026-39834

A flaw was found in golang.org/x/crypto/ssh. When a remote attacker attempts to write data larger than 4GB in a single call on an SSH Secure Shell channel, an integer overflow occurs in the internal payload size calculation. This vulnerability causes the write loop to spin indefinitely,...

CVE-2026-5477

An integer overflow existed in the wolfCrypt CMAC implementation, that could be exploited to forge CMAC tags. The function wcCmacUpdate used the guard if cmac-totalSz != 0 to skip XOR-chaining on the first block where digest is all-zeros and the XOR is a no-op. However, totalSz is word32 and wrap...

SUSE CVE-2026-39834

When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent truncation...

CVE-2026-39834 Invoking infinite loop on large channel writes in golang.org/x/crypto/ssh

When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent truncation...

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: RISCV: Fixed TASKSIZE on 64-bit NOMMU. On NOMMU, user space memory can originate from anywhere within physical RAM. The current definition of TASKSIZE is incorrect if any RAM exceeds 4GB, causing spurious failures in user space...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: libbpf: Handling of size overflow for ringbuf mmap The maximum size of a ringbuf on an x86-64 host is 2GB. Therefore, 2 maxentries will cause an overflow of type u32 when mapping producer pages and data pages. Simply casting...
