- CVE-2026-92248A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution.7.8
- CVE-2026-92255Netcore NR255-V version 1.5.130703 contains an out-of-bounds read vulnerability in filter_arp_put_file.cgi caused by improper use of a string handling API. Attackers can trigger an unterminated buffer over-read by exploiting this flaw in the affected component, potentially exposing adjacent memory contents.5.3
