  CVE-2026-32282

  TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix

  On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_N…

  Usage of IPv6 zone IDs can bypass URI name constraints in crypto/x509

  A certificate with a URI which has a IPv6 address with a zone ID may incorrectly satisfy a URI name constraint that applies to the certificate chain. Certificates containing URIs are not permitted in the web PKI, so this only affects users of private PKIs whi…
