Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: EFI: In runtime mode, a potential overflow of the size of the soft-reserved region has been fixed. If there are pages worth ≥ 4GB in a soft-reserved region, the value of mdsize will be reduced...

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 found in Linux 5.10, Linux 5.15

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...

Astra Linux – Vulnerability in python-cryptography

In the cryptography package for Python before version 3.3.2, certain sequences of update calls to symmetrically encrypt multi-GB values could lead to integer overflows and buffer overflows, as demonstrated by the Fernet class...

nodejs: Node.js WebCrypto: Denial of Service via large input to subtle.encrypt()

A flaw was found in the Node.js WebCrypto implementation. A remote attacker could exploit this vulnerability by providing an input to the subtle.encrypt function that is a multiple of 2 gigabytes GiB. This could lead to a denial of service DoS by crashing the Node.js process...

📄 DCMTK 3.7.0 XML Binary File Heap Buffer Overflow

In DCMTK DICOM ToolKit version 3.7.0, the xml2dcm application and the DcmXMLReader library are vulnerable to a heap buffer overflow when importing external binary files larger than 4 GiB via the binary="file" XML attribute. The file size is measured as sizet but narrowed to Uint32 for the heap...

Brazil Health Surveillance Database Exposed 79GB of Sensitive Records

Brazil's SISVISA health surveillance system left 102,215 files totaling 79GB open online, including tax IDs and identity documents, without password protection...

JLSEC-2026-1133 Issue summary: Parsing a crafted DER-encoded ASN.1 structure with a primitive element whose...

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...

CVE-2026-16280

An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in...

K000162338: PHP vulnerability CVE-2025-6491

Security Advisory Description In PHP versions:8.1. before 8.1.33, 8.2. before 8.2.29, 8.3. before 8.3.23, 8.4. before 8.4.10 when parsing XML data in SOAP extensions, overly large 2Gb XML namespace prefix may lead to null pointer dereference. This may lead to crashes and affect the availability o...

PYSEC-2026-2972 py7zr: Decompression bomb (zip bomb) denial of service via unchecked extraction size

py7zr's Worker.decompress extracts archive entries without tracking total decompressed size. A crafted .7z file can exhaust disk or memory before the extraction completes. Measured: 15.6 KB archive → 100 MB output 6,556:1 ratio. Proof of concept: python import py7zr, tempfile, os create bomb:...

Scrapy is vulnerable to a denial of service (DoS) attack due to flaws in brotli decompression implementation

Scrapy versions up to 2.13.3 are vulnerable to a denial of service DoS attack due to a flaw in its brotli decompression implementation. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of...

CVE-2026-54903

A flaw was found in Oj, an Optimized JSON JavaScript Object Notation parser for Ruby. This vulnerability allows a remote attacker to cause heap corruption and a denial of service DoS by providing a JSON string larger than 2 gigabytes GB. An integer overflow occurs when processing the string lengt...
