  "description": "In the Linux kernel, the following vulnerability has been resolved:  staging: rtl8723bs: fix OOB read in rtw_restruct_wmm_ie()  rtw_restruct_wmm_ie() scans in_ie for a WMM IE with:  \twhile (i \u003C in_len) { \t\t... \t\tif (i \u002B 5 \u003C in_len \u0026\u0026 in_ie[i] == 0xDD \u0026\u0026 ...) { \t\t\t... \t\t\tbreak; \t\t} \t\ti \u002B= (in_ie[i \u002B 1] \u002B 2); /* to the next IE element */ \t}  When the \u0022i \u002B 5 \u003C in_len\u0022 match check fails simply because i is within 5 bytes of the end of the buffer (i.e. no WMM IE was found near the tail of in_ie), execution falls through to \u0022i \u002B= (in_ie[i \u002B 1] \u002B 2)\u0022, which reads in_ie[i \u002B 1]. If i == in_len - 1 at that point, this is a 1-byte out-of-bounds read of an attacker-influenced IE buffer built from association/scan data.  Commit a75281626fc8f (\u0022staging: rtl8723bs: fix potential out-of-bounds read in rtw_restruct_wmm_ie\u0022) added the \u0022i \u002B 5 \u003C in_len\u0022 guard to the match condition itself, but did not add an equivalent guard before the fallthrough advance, so the same class of OOB read remained reachable through the non-matching path.  Add an explicit bounds check before advancing to the next IE.",
