CVE-2026-49427

Pages belonging to largepage shared memory objects were not explicitly wired. When sendfile2 transmitted such an object with the SFNOCACHE flag, it freed the underlying pages after transmission even though existing mappings still referred to them. An unprivileged local user can abuse the bug to...

CVE-2026-49427 posixshm: largepage shared memory objects not explicitly wired

CVE-2026-49427

CVE-2026-49427 is a use-after-free vulnerability in FreeBSD's POSIX largepage shared memory objects (posixshm module). Pages in largepage objects were not explicitly wired, so when sendfile(2) transmitted such an object with the SF_NOCACHE flag, it freed underlying pages while existing mappings s...

goshs has ACL Bypass & Path Traversal

Summary sendFile derives the served filename from the raw request path while opening the file from the cleaned path, so appending a trailing slash empties the derived name and defeats both the never-serve rule for the ACL file and the block list. Finding Medium: trailing-slash ACL and hidden-file...

CVE-2026-45257

The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile2, which can reference file-backed memory directly through non-anonymous MEXTPG pages or...

CVE-2026-45257

CVE-2026-45257 : FreeBSD KTLS receive path decrypts in place, enabling an unprivileged local user to overwrite a file’s page cache via sendfile(2) data over a loopback connection when KTLS receive is enabled. This can corrupt the backing file and allow privilege escalation by overwriting setuid/t...

CVE-2026-7381

A flaw was found in Plack::Middleware::XSendfile. A remote attacker can exploit this vulnerability by manipulating HTTP headers, specifically X-Sendfile-Type and X-Accel-Mapping, when the application is deployed behind an nginx reverse proxy. This client-controlled path rewriting could allow the...
