CVE-2026-39461

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-2026-6477

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...
