GHSA-GCR9-247M-6CPP

Vulnerability from github – Published: 2024-04-03 18:30 – Updated: 2025-03-03 18:31

Details

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

scsi: target: pscsi: Fix bio_put() for error case

As of commit 066ff571011d ("block: turn bio_kmalloc into a simple kmalloc wrapper"), a bio allocated by bio_kmalloc() must be freed by bio_uninit() and kfree(). That is not done properly for the error case, hitting WARN and NULL pointer dereference in bio_free().

Severity

5.5 (Medium)

No local access is needed.\nAC:L - The failure path is entered deterministically by choosing a transfer length that exceeds the backing device\u0027s max_hw_sectors/max_segments, making the second blk_rq_append_bio() fail; the attacker fully controls this value and can also tune it so bi_max_vecs lands in the range that triggers the invalid kmem_cache_free.\nPR:N - passthrough_parse_cdb() applies no length validation, and an iSCSI initiator needs no secret \u2014 LIO demo mode (generate_node_acls/authentication=0) admits any initiator, and even with ACLs the initiator IQN is a self-declared string, not a credential.\nUI:N - The bug is triggered entirely by an attacker-sent SCSI command processed in the target\u0027s command path; no action by any local user or administrator is required.\nS:U - The invalid free and the resulting corruption/oops are confined to the host kernel, which is both the vulnerable and the impacted component; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - bvec_free() frees an interior pointer of the kmalloc\u0027d bio into an unrelated biovec kmem_cache, splicing a kmalloc slab onto that cache\u0027s freelist and producing cross-cache overlapping allocations that can be groomed into an arbitrary kernel-memory read.\nI:H - The same invalid free is a slab-corruption primitive \u2014 biovec objects handed out over live kmalloc memory give type confusion and a write primitive over adjacent kernel objects, exploitable for control-flow hijack.\nA:H - bio_free() unconditionally dereferences the NULL bio_set via bs-\u003efront_pad, producing a WARN plus a guaranteed NULL pointer dereference oops in the target command path on every trigger, repeatable by the remote attacker (immediate panic with panic_on_oops/panic_on_warn)."
