Not enough EPSS history yet.
Integer wraparound in PostgreSQL generation memory contexts allows a database user to execute arbitrary code as the operating system user running the database, via freeing an allocation larger than 1 GB and causing its block to be reused for smaller chunks whose back-pointer offset cannot represent that position. Within major versions 16-18, minor versions before PostgreSQL 18.7, 17.12, and 16.16 are affected. Versions before PostgreSQL 16 are unaffected.

——0A flaw was found in BusyBox. An integer overflow occurs in the volume_id component when calculating buffer boundaries while probing filesystem metadata. An attacker can exploit this vulnerability by providing a specially crafted filesystem image on an attached storage device. When probed by utilities such as blkid, findfs, or mount, the application crashes, resulting in a Denial of Service (DoS) that prevents the system from resolving or mounting storage devices.1dCVE-2026-636608.1 HIG35.7%
——11node-fontnik is a library that delivers a range of glyphs rendered as SDFs (signed distance fields) in a protocol buffer. Prior to version 0.7.7, a crafted font could trigger a heap out-of-bounds write in RenderSDF (include/mapbox/glyph_foundry_impl.hpp). RenderSDF computed the SDF bitmap allocation size as buffered_width * buffered_height in 32-bit unsigned int. Glyph dimensions are derived from the uploaded font's outline bounding box with no upper bound, so a glyph large enough to make that product exceed 2³² wrapped to a small value. The buffer was then under-allocated while the render loop still wrote one byte per pixel, corrupting the heap (CWE-190 → CWE-787) and crashing the process. A 680-byte font is enough to drive FreeType to a 65536×65536 buffered glyph, wrapping the size to 0. This issue has been patched in version 0.7.7.2d
