In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: initialize le_tmp64 in rtw_BIP_verify() Initialize le_tmp64 to zero in rtw_BIP_verify() to prevent using uninitialized data. Smatch warns that only 6 bytes are copied to this 8-byte (u64) variable, leaving the last two bytes uninitialized: drivers/staging/rtl8723bs/core/rtw_security.c:1308 rtw_BIP_verify() warn: not copying enough bytes for '&le_tmp64' (8 vs 6 bytes) Initializing the variable at the start of the function fixes this warning and ensures predictable behavior.

A flaw was found in the Linux kernel's rtl8723bs Wi-Fi driver. This vulnerability occurs within the rtw_BIP_verify() function, where a variable is not fully initialized, leaving two bytes with unpredictable values. This uninitialized data can lead to unpredictable system behavior, potentially resulting in a denial of service (DoS) or information disclosure.
