CVE-2026-39461: Stack-based Buffer Overflow

libcasper3 communicates with helper processes via UNIX domain sockets, and uses the select2 system call to wait for data to become available. However, it does not verify that its socket descriptor fits within select2's descriptor set size limit of FDSETSIZE 1024. An attacker able to cause an...

CVE-2026-39457: Stack-based Buffer Overflow

When exchanging data over a socket, libnv uses select2 to wait for data to arrive. However, it does not verify whether the provided socket descriptor fits in select2's file descriptor set size limit of FDSETSIZE 1024. An attacker who is able to force a libnv application to allocate large file...
