CVE-2026-111148 Details
Description
libsidplayfp through 3.1.1 contains a heap out-of-bounds read vulnerability that allows attackers to crash applications by supplying a PSID/RSID file with an unchecked data offset. Attackers can set the header data offset beyond the file size, wrapping the length calculation so resolveAddrs() reads up to 64 KiB past the heap buffer.
A heap out-of-bounds read vulnerability has been identified in libsidplayfp versions through 3.1.1. This vulnerability allows attackers to crash applications by providing a PSID or RSID file with an unchecked data offset. The issue arises because the header data offset can be set beyond the file size, causing a length calculation underflow. As a result, the 'resolveAddrs' function reads up to 64 KiB past the end of the heap buffer, leading to a potential denial-of-service condition.
Users can update to libsidplayfp version 3.1.1 or later, where this vulnerability has been fixed.
