CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's qcom_battmgr component, specifically in how it handles string termination when copying firmware data. This flaw can lead to memory corruption, as improperly terminated strings may overwrite adjacent memory areas, potentially exposing sensitive information or causing system instability. Organizations using affected Linux kernel versions, particularly those deploying devices reliant on Qualcomm battery management, should prioritize addressing this issue to mitigate risks associated with memory corruption and data leakage.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: power: supply: qcom_battmgr: terminate the strings from firmware The qcom_battmgr_sc8280xp_strcpy() takes a Pascal-style string when the firmware sends one. Otherwise it copies all BATTMGR_STRING_LEN bytes and leaves the destination without a terminator. Those destinations are model_number, serial_number and oem_info, each BATTMGR_STRING_LEN and declared next to each other. They go out to user space as val->strval, which power_supply_format_property() prints with "%s", so a firmware string that fills the whole field makes that read run into the following members. Use strscpy() so the copy always terminates, the way the SM8350 path already does for the same field.
