In PHP versions 8.2. before 8.2.31, 8.3. before 8.3.31, 8.4. before 8.4.21, and 8.5. before 8.5.6, the metaphone function in ext/standard/metaphone.c uses a signed int variable to track the current position within the input string. If a string longer than 2,147,483,647 bytes is passed, a signed...

CVE-2026-43368

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix potential overflow of shmem scatterlist length When a scatterlists table of a GEM shmem object of size 4 GB or more is populated with pages allocated from a folio, unsigned int .length attribute of a scatterlist may...

CVE-2026-43368

The CVE-2026-43368 entry concerns the Linux kernel DRM/i915 component (GEM shmem objects). A overflow can occur in the unsigned int .length field of a scatterlist when a scatterlists table for a GEM shmem object of 4 GB or more is built from folio-allocated pages, causing the total byte length of...

SUSE CVE-2026-43080

In the Linux kernel, the following vulnerability has been resolved: l2tp: Drop large packets with UDP encap syzbot reported a WARN on my patch series 1. The actual issue is an overflow of 16-bit UDP length field, and it exists in the upstream code. My series added a debug WARN with an overflow...

CVE-2026-43080

A flaw was found in the Linux kernel's L2TP Layer 2 Tunneling Protocol subsystem. This vulnerability allows a remote attacker to send an oversized PPPoL2TP packet with UDP encapsulation. Due to an overflow in the 16-bit UDP length field, the packet's length is incorrectly truncated, which can lea...
