Synapse CPU starvation (Denial of Service)

Impact Local authenticated users can cause Synapse to starve other requests of CPU and lead to other requests failing, causing other users to be denied service. Homeservers that trust all their local users are not at risk. Patches Update to Synapse 1.152.1 or later. Workarounds If Synapse is...

CVE-2026-43392

Summary (CVE-2026-43392) : In the Linux kernel, the sched_ext vulnerability causes a potential DoS by starving the enable path in scx_enable() when fair-class workloads saturate the system. The root cause is a switch of the calling thread’s sched_class from fair to ext during the READY→ENABLED lo...

CVE-2026-31574

CVE-2026-31574 concerns the Linux kernel clockevents subsystem. The issue arises from missing resets of the next_event_forced flag in several code paths, including during clock event state changes, when arming a non-forced event, and in the suspend wakeup handler. This can leave the flag stale ac...
