CVE-2026-99249

In the Linux kernel, the following vulnerability has been resolved: pidnamespace: make zappidnsprocesses freezable When the init of a pid namespace exits, zappidnsprocesses waits until all other pids in the namespace are freed. A tracer outside the namespace that does not reap its traced zombies...

CVE-2026-99249

In the Linux kernel , a vulnerability in pid_namespace was identified where the zap_pid_ns_processes() function would cause suspend attempts to fail. When the init of a pid namespace exits, this function waits for all other pids in the namespace to be freed. However, if an external tracer fails t...

In the Linux kernel, the following vulnerability has been resolved: pidnamespace: prevent TIFNOTIFYSIGNAL from interrupting the reaper Since commit 7fea700e04bd "zappidnsprocesses: clear TIFNOTIFYSIGNAL along with TIFSIGPENDING" zappidnsprocesses clears TIFNOTIFYSIGNAL before every kernelwait4...

CVE-2026-99244

The Linux kernel contains a vulnerability in the pid_namespace where the reaper could enter a busy-wait state. This occurs because kernel_wait4() does not sleep and returns -ERESTARTSYS if signal_pending() is true. Previous attempts to clear TIF_NOTIFY_SIGNAL were insufficient as it could be re-r...
