  "details": "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-\u003elength + 2) each iteration but only guards on i \u003c 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-\u003elength from one byte past the allocated receive buffer.  Additionally, even when the header bytes are in bounds, pIE-\u003elength itself can extend the data window beyond len, passing a truncated IE to the handler functions.  Add two guards at the top of the loop body:   1. Break if fewer than sizeof(*pIE) bytes remain (can't read header).   2. Break if the IE's declared data extends past len.  Also replace i += (pIE-\u003elength + 2) with i += sizeof(*pIE) + pIE-\u003elength for consistency with the sizeof(*pIE) guards added above.",
