Summary

In the Linux kernel, the following vulnerability has been resolved: bpf: bpf_local_storage: Always use bpf_mem_alloc in PREEMPT_RT In PREEMPT_RT, kmalloc(GFP_ATOMIC) is still not safe in non preemptible context. bpf_mem_alloc must be used in PREEMPT_RT. This patch is to enforce bpf_mem_alloc in the bpf_local_storage when CONFIG_PREEMPT_RT is enabled. [ 35.118559] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 [ 35.118566] in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1832, name: test_progs [ 35.118569] preempt_count: 1, expected: 0 [ 35.118571] RCU nest depth: 1, expected: 1 [ 35.118577] INFO: lockdep is turned off. ...

The verifier has ensured GFP_KERNEL is passed only in sleepable context. It has been an old issue since the first introduction of the bpf_local_storage ~5 years ago, so this patch targets the bpf-next. bpf_mem_alloc is needed to solve it, so the Fixes tag is set to the commit when bpf_mem_alloc was first used in the bpf_local_storage.

PREEMPT_RT is fully mainline since 6.12 and is the standard configuration for the automotive, industrial-control and robotics deployments this subsystem serves, so the attacker simply selects such a target.\nPR:L - An unprivileged local user with delegated BPF access (BPF token in a user namespace, the supported container delegation model for CAP_BPF/CAP_PERFMON) can create the storage map and load the tracing program. This matches the established PR:L scoring for BPF-reachable kernel flaws in this CNA\u0027s prior assignments.\nUI:N - The attacker loads and triggers its own BPF program and generates the socket state transitions itself; no action by any other user or administrator is needed.\nS:U - The fault and its consequences are confined to the kernel\u0027s own security authority \u2014 no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Blocking on an rtmutex inside a preempt-disabled RCU-sched read section lets a grace period elapse mid-probe, so the tracepoint\u0027s deferred free can release tp_funcs while it is still being walked \u2014 a use-after-free on attacker-groomed heap memory that yields a kernel read primitive.\nI:H - The same premature-free window plus the corruption of per-CPU state that the preempt_disable was protecting (bpf_prog_active, kprobe control block, cpu_slab) gives a write primitive suitable for control-flow hijacking, matching the C:H/I:H treatment of the prior PREEMPT_RT BPF flaw CVE-2025-21825.\nA:H - At minimum the kernel emits a \"BUG: sleeping function called from invalid context\" splat on every trigger, and the uncontended-debug-off path schedules while atomic, which can deadlock or hang the machine and destroys the latency guarantees that define an RT deployment."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
