  "details": "In the Linux kernel, the following vulnerability has been resolved:  slip: bound decode() reads against the compressed packet length  slhc_uncompress() parses a VJ-compressed TCP header by advancing a pointer through the packet via decode() and pull16(). Neither helper bounds-checks against isize, and decode() masks its return with \u0026 0xffff so it can never return the -1 that callers test for -- those error paths are dead code.  A short compressed frame whose change byte requests optional fields lets decode() read past the end of the packet. The over-read bytes are folded into the cached cstate and reflected into subsequent reconstructed packets.  Make decode() and pull16() take the packet end pointer and return -1 when exhausted. Add a bounds check before the TCP-checksum read. The existing == -1 tests now do what they were always meant to.",
