CVE-2026-43390

   
Software afectado LINUX KERNEL
 
In the Linux kernel, the following vulnerability has been resolved:

nstree: tighten permission checks for listing

Even privileged services should not necessarily be able to see other
privileged service's namespaces so they can't leak information to each
other. Use may_see_all_namespaces() helper that centralizes this policy
until the nstree adapts.
