- Summary
- CVE-2026-31626 affecting package kernel for versions less than 6.6.137.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: initialize letmp64 in rtwBIP_verify()
Initialize letmp64 to zero in rtwBIP_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/rtwsecurity.c:1308 rtwBIPverify() warn: not copying enough bytes for '&letmp64' (8 vs 6 bytes)
Initializing the variable at the start of the function fixes this warning and ensures predictable behavior.
