Kernel memory disclosure via unchecked gain index
Published Feb 27, 2025 · Updated May 12, 2026
Out-of-bounds read in the Linux brcmsmac wireless driver allows local users to disclose kernel memory or crash the system. The wlc_phy_iqcal_gainparams_nphy() function uses a gain value to index tbl_iqcal_gainparams_nphy without first checking the table range. Local access and a system using the affected brcmsmac Broadcom wireless path are required, and the bounded consequences are memory disclosure and service interruption.
