How to fix?

Upgrade SLES:15.7 kernel-livepatch-6_4_0-150700_7_67-rt to version 1-150700.1.5.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_7_67-rt package and not the kernel-livepatch-6_4_0-150700_7_67-rt package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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.
