UBUNTU-CVE-2026-88351

An integer overflow vulnerability exists in the MPack Node API in MPack 1.1.1 on 32-bit platforms. When parsing a specially crafted MessagePack array32 or map32 object with an excessively large element count, the page allocation size calculation in mpacktreeparsechildren can overflow sizet and...

kernel: sctp: prevent peer transport count overflow

A flaw was found in the Stream Control Transmission Protocol SCTP implementation within the Linux kernel. An integer overflow occurs when the transportcount for an association exceeds its 16-bit limit, causing it to wrap around to zero. This allows a diagnostic dump to write 8 MiB of peer address...

libxml2: libxml2: Arbitrary code execution via heap-based buffer overflow

A flaw was found in libxml2, a software library for parsing XML documents. An integer overflow within the xmlDictAddQString function can lead to a heap-based buffer overflow. This vulnerability could allow a local attacker to execute arbitrary code on the system, potentially compromising its...

libxml2: libxml2: Data integrity issues due to integer overflow in write callbacks

An integer overflow in the libxml2 xmlIO module occurs when data backlogs exceed maximum integer limits. This flaw passes negative length values to downstream write callbacks, creating an unsafe state that can lead to data corruption or compromise application confidentiality and integrity...

Important: Red Hat Security Advisory: libxml2 security update

libxml2: libxml2: Heap-based buffer overflow in xmlXPtrEval due to xpointer length saturation

A flaw in libxml2's xmlXPtrEvalXPtrPart function allows a local attacker to cause a heap-based buffer overflow. An integer overflow while processing an oversized xpointer expression leads to incorrect memory allocation and an out-of-bounds write, potentially resulting in information disclosure,...

poppler: Poppler: Remote integer overflow vulnerability

A flaw was found in Poppler. This vulnerability, an integer overflow, occurs within the JBIG2Stream::readCodeTableSeg function when processing specially crafted JBIG2 image data. A remote attacker could exploit this by providing specially crafted input, which may lead to memory corruption. This...
