pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...

CVE-2026-31616

A flaw was found in the Linux kernel's USB gadget Phonet function. A remote attacker, acting as a malicious USB host, could exploit this vulnerability by sending a continuous stream of full-page data transfers. This action causes an overflow in the kernel's internal data structures, leading to...

libpng: libpng: Arbitrary code execution due to use-after-free vulnerability

A flaw was found in libpng, a library used for processing PNG Portable Network Graphics image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can...

CVE-2026-40572

NovumOS is a custom 32-bit operating system written in Zig and x86 Assembly. In versions prior to 0.24, Syscall 15 MemoryMapRange allows Ring 3 user-mode processes to map arbitrary virtual address ranges into their address space without validating against forbidden regions, including critical...

curl: Stack exhaustion in MIME multipart reading with deeply nested subparts

Summary: The MIME read path uses mutually recursive helpers for nested multipart structures without enforcing a recursion depth limit. A sufficiently deep tree of nested curlmimesubparts objects causes stack exhaustion when libcurl starts reading the MIME body. The attached PoC builds a deeply...
