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.
