CVE-2024-58014: wifi: brcmsmac: add gain range check to wlc_phy_iqcal_gainparams_nphy()

In the Linux kernel, the following vulnerability has been resolved: wifi: brcmsmac: add gain range check to wlc_phy_iqcal_gainparams_nphy() In 'wlc_phy_iqcal_gainparams_nphy()', add gain range check to WARN() instead of possible out-of-bounds 'tbl_iqcal_gainparams_nphy' access. Compile tested only. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel Wi-Fi driver bug in brcmsmac. A missing gain range check could allow an out-of-bounds table access. The sources do not provide CVSS, exploitability, or observed exploitation evidence, so business urgency depends on whether affected Linux systems use this Broadcom wireless driver.

Executive priority

Handle through normal kernel patch management unless asset inventory shows broad brcmsmac usage or exposed appliance fleets. There is insufficient evidence for emergency response, but affected endpoints and embedded devices should not be left untracked.

Technical view

The fix adds a gain range check in wlc_phy_iqcal_gainparams_nphy() to avoid possible out-of-bounds access to tbl_iqcal_gainparams_nphy. The kernel note says the change was compile-tested only and found by SVACE through Linux Verification Center.

Likely exposure

Exposure appears limited to Linux systems with the brcmsmac Wi-Fi driver present and reachable in affected kernel versions. Servers without Broadcom Wi-Fi hardware or without this driver loaded are less likely to be exposed, but confirm against actual kernels and modules.

Exploitation context

The bundle marks KEV as false and provides no cited evidence of active exploitation, public exploit use, or a working proof of concept. Treat exploitation status as unconfirmed rather than absent.

Researcher notes

Key unknowns are impact severity, trigger conditions, and whether out-of-bounds access is practically attacker-controllable. The upstream text only states possible out-of-bounds access and compile-tested remediation, so validation should focus on code lineage and driver presence.

Mitigation direction

  • Inventory Linux systems using the brcmsmac driver or Broadcom Wi-Fi hardware.
  • Apply vendor kernel updates that include the referenced stable fixes.
  • Review Debian LTS and device vendor advisories for packaged update availability.
  • For appliances, follow Siemens or vendor-specific guidance where applicable.

Validation and detection

  • Check running kernel versions against affected and fixed vendor package versions.
  • Confirm whether brcmsmac is installed, loadable, or currently loaded.
  • Verify updated kernels include the relevant stable commit for their branch.
  • Prioritize laptops, embedded systems, and appliances with Broadcom Wi-Fi hardware.
