CVE-2026-64443

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix OOB read in update_beacon_info() IE loop The IE parsing loop in update_beacon_info() advances by (pIE->length + 2) each iteration but only guards on i < len. When a malicious AP sends a Beacon whose last IE has only one byte remaining in the frame (the element_id byte lands at len-1), the loop reads pIE->length from one byte past the allocated receive buffer. Additionally, even when the header bytes ar
