CVE-2026-89518

This CVE affects the Linux kernel 's sched_ext (BPF scheduler extension) subsystem. Under core scheduling , ops.dispatch() may execute on a CPU different from the dispatched run queue's, but several kfunc paths incorrectly assumed this_rq() always coincides with the dispatched rq. Specifically, s...

CVE-2026-74715

A flaw was found in the kernel. A reference imbalance vulnerability exists in the Berkeley Packet Filter BPF conntrack kfuncs. This occurs when the 'opts' argument, which can point to a shared map value, has its network namespace identifier netnsid read separately during reference acquisition and...
