CVE-2024-58014 is an out-of-bounds read vulnerability in the Linux kernel Broadcom brcmsmac Wi-Fi driver. The flaw is in wlc_phy_iqcal_gainparams_nphy(), which could use an insufficiently validated gain value to index the tbl_iqcal_gainparams_nphy calibration table. The upstream fix adds gain-range validation to the WARN() condition before the table access.

Linux kernel brcmsmac Wi-Fi gain-range validation flaw.
An out-of-bounds access vulnerability in the Linux kernel brcmsmac Wi-Fi driver function wlc_phy_iqcal_gainparams_nphy(). The fix adds validation of the gain range before accessing the tbl_iqcal_gainparams_nphy table.
A Linux kernel brcmsmac Wi-Fi driver out-of-bounds read (CWE-125) caused by insufficient validation of gain values in wlc_phy_iqcal_gainparams_nphy(). It can expose memory or crash the system. Red Hat rates it Moderate (CVSS 6.0); NVD scores it 7.1. Exploitation requires local access, no user interaction, and high privileges according to Red Hat's vector.
An out-of-bounds access vulnerability in the Linux kernel's Broadcom brcmsmac wireless-driver PHY code. The flaw occurs when wlc_phy_iqcal_gainparams_nphy() does not validate a gain value before accessing tbl_iqcal_gainparams_nphy.
