CVE-2026-39457 Stack overflow via select() file descriptor set 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...

CVE-2026-39457

CVE-2026-39457 concerns the libnv library. The issue arises when exchanging data over a socket: libnv uses select(2) but does not verify that the socket descriptor fits within FD_SETSIZE (1024). This can allow an attacker to cause stack corruption by forcing a process to allocate many file descri...
