It fails to verify that there is enough space remaining for the\nfixed 8-byte header of the structure.\n\nIf a server provides a DataOffset that leaves less than 8 bytes remaining,\nthe check passes, but subsequent reads of ReparseTag and ReparseDataLength\nwill occur out-of-bounds.\n\nFix this by ensuring the remaining space is at least the size of the\nreparse_data_buffer structure before accessing its fields.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3d67f155fe5813cfb02a551a9a12d6ea06a902e9","tags":[]},{"url":"https://git.kernel.org/stable/c/5f0306e731e2f46e91419eae57eee3a241c055e0","tags":[]},{"url":"https://git.kernel.org/stable/c/8dc5db3a0e583ea8d31d0613cefd99e93e095c3c","tags":[]},{"url":"https://git.kernel.org/stable/c/d1152c96a3002e3df6b9a5b007cecaa7b19b4f79","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
