CVE-2023-54108 — scsi: qla2xxx: Fix DMA-API call trace on NVMe LS requests

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix DMA-API call trace on NVMe LS requests The following message and call trace was seen with debug kernels: DMA-API: qla2xxx 0000:41:00.0: device driver failed to check map error [device address=0x00000002a3ff38d8] [size=1024 bytes] [mapped as single] WARNING: CPU: 0 PID: 2930 at kernel/dma/debug.c:1017 check_unmap+0xf42/0x1990 Call Trace: debug_dma_unmap_page+0xc9/0x100 qla_nvme_ls_unmap+0x141/0x210 [qla2xxx] Remove DMA mapping from the driver altogether, as it is already done by FC layer. This prevents the warning.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+2

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Linux Linux).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes, errors and authentication anomalies.

Affected scope

Vendor, product and versions as the sources word them.

What should defenders know first?

CVE-2023-54108 is "scsi: qla2xxx: Fix DMA-API call trace on NVMe LS requests", rated Unknown. It affects Linux (Linux); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. EPSS 0.21% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
