Vulnerability from github – Published: 2024-06-19 15:30 – Updated: 2025-10-03 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

openrisc: traps: Don't send signals to kernel mode threads

OpenRISC exception handling sends signals to user processes on floating point exceptions and trap instructions (for debugging) among others. There is a bug where the trap handling logic may send signals to kernel threads, we should not send these signals to kernel threads, if that happens we treat it as an error.

This patch adds conditions to die if the kernel receives these exceptions in kernel mode code.

Severity

5.5 (Medium)

No network or adjacent-network path reaches `arch/openrisc/kernel/traps.c`.\nAC:L - The attacker fully controls the FPCSR value written to the SPR by the kernel-mode `l.mtspr` in `RESTORE_ALL`/`_switch`, so the kernel-mode exception is raised deterministically on every attempt; there is no race and no memory-layout dependence.\nPR:L - Any unprivileged local user can do this \u2014 `sigreturn` on a self-delivered signal needs no capability, and `ptrace` of one\u0027s own child needs none either; no CAP_SYS_ADMIN or root gate exists on the path into `do_fpe_trap()`/`do_trap()`.\nUI:N - The attacking process triggers the kernel-mode exception entirely on its own via a syscall return path; no other user or victim action is involved.\nS:U - The corruption and the crash are confined to the kernel of the same machine; no VM, IOMMU, or other security-authority boundary is crossed.\nC:H - `force_sig_fault()` hands userspace a kernel text address in `si_addr` (`regs-\u003epc` of the supervisor-mode fault), and the clobbered `EPCR`/`ESR` cause the kernel to resume in supervisor mode with attacker-controlled registers and a user-controlled `r1`, from which kernel memory can be read out.\nI:H - Because the nested kernel-mode exception overwrites `EPCR`/`ESR` mid-`RESTORE_ALL`, the subsequent `l.rfe` returns into kernel code with `SR.SM` still set and the user\u0027s register file loaded, giving a supervisor-mode stack-pivot/state-corruption primitive rather than a clean fault.\nA:H - The signal is never delivered (the kernel-mode return path skips `do_work_pending`), so the faulting `mtspr` is re-executed and the exception re-fires in an unkillable supervisor-mode loop that hangs the CPU \u2014 and on the fixed kernel the same condition is a `die()`/oops."

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.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
