In the Linux kernel, the following vulnerability has been resolved:[EOL][EOL]crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg[EOL][EOL]Issuing two writes to the same af_alg socket is bogus as the[EOL]data will be interleaved in an unpredictable fashion. Furthermore,[EOL]concurrent writes may create inconsistencies in the internal[EOL]socket state.[EOL][EOL]Disallow this by adding a new ctx->write field that indiciates[EOL]exclusive ownership for writing.
