  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB read in rtw_restruct_wmm_ie()\n\nrtw_restruct_wmm_ie() scans in_ie for a WMM IE with:\n\n\twhile (i \u003c in_len) {\n\t\t...\n\t\tif (i + 5 \u003c in_len \u0026\u0026 in_ie[i] == 0xDD \u0026\u0026 ...) {\n\t\t\t...\n\t\t\tbreak;\n\t\t}\n\t\ti += (in_ie[i + 1] + 2); /* to the next IE element */\n\t}\n\nWhen the \"i + 5 \u003c in_len\" match check fails simply because i is\nwithin 5 bytes of the end of the buffer (i.e. no WMM IE was found\nnear the tail of in_ie), execution falls through to\n\"i += (in_ie[i + 1] + 2)\", which reads in_ie[i + 1]. If i == in_len\n- 1 at that point, this is a 1-byte out-of-bounds read of an\nattacker-influenced IE buffer built from association/scan data.\n\nCommit a75281626fc8f (\"staging: rtl8723bs: fix potential\nout-of-bounds read in rtw_restruct_wmm_ie\") added the \"i + 5 \u003c\nin_len\" guard to the match condition itself, but did not add an\nequivalent guard before the fallthrough advance, so the same class\nof OOB read remained reachable through the non-matching path.\n\nAdd an explicit bounds check before advancing to the next IE.",
