kernel: KVM: x86: Check for invalid/obsolete root *after* making MMU pages available

A flaw was found in KVM in the Linux kernel. This vulnerability occurs due to improper validation of memory management unit MMU page roots after these pages are made available. An attacker could exploit this by triggering a scenario where KVM attempts to map memory into an invalid root, causing...

UBUNTU-CVE-2026-58403

Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile...
