CVE-2026-45536

CVE-2026-45536 affects Netty, specifically Unix-domain socket fd reception in netty_unix_socket_recvFd. Prior to versions 4.1.135.Final and 4.2.15.Final, a peer-sent SCM_RIGHTS message containing two fds can cause both descriptors to leak due to a mismatch between cmsg_len checks and the actual f...

PT-2026-47581

netty unix socket recvFd sets msg control to char controlCMSG SPACEsizeofint line 940 — 24 bytes on 64-bit Linux. A peer-sent SCM RIGHTS cmsg carrying two ints has cmsg len = CMSG LEN8 = 24, which fits exactly with no MSG CTRUNC, so the kernel installs both fds in the receiving process. The...
