UBUNTU-CVE-2026-43402

In the Linux kernel, the following vulnerability has been resolved: kthread: consolidate kthread exit paths to prevent use-after-free Guillaume reported crashes via corrupted RCU callback function pointers during KUnit testing. The crash was traced back to the pidfs rhashtable conversion which...

PT-2026-41580

An issue was discovered in Mbed TLS versions from 2.19.0 up to 3.6.5, Mbed TLS 4.0.0. Insufficient protection of serialized SSL context or session structures allows an attacker who can modify the serialized structures to induce memory corruption, leading to arbitrary code execution. This is cause...

CVE-2026-25589

RedisBloom is a probabilistic data structures module for Redis. In all versions of RedisBloom before 2.8.20, the module does not properly validate serialized values processed through the Redis RESTORE command. An authenticated attacker with permission to execute RESTORE on a server with the...

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...

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...

MuPDF is a lightweight PDF viewer and toolkit written in portable C. The renderer in MuPDF is tailored for high quality anti-aliased graphics. MuPDF renders text with metrics and spacing accurate to within fractions of a pixel for the highest fidelity in reproducing the look of a printed page on...

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...

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...

CVE-2026-40572 NovumOS has Arbitrary Memory Mapping via Syscall 15 (MemoryMapRange)
