Missing NULL Checks for Buffer Allocations

Critical: Missing NULL Checks for Buffer Allocations

Priority: CRITICAL

Type: Memory Safety

Location

libwsv5.c line 1772-1775 in obsws_connect()

Issue

Buffer allocations are not checked for NULL before use:

conn->recv_buffer_size = OBSWS_DEFAULT_BUFFER_SIZE;
conn->recv_buffer = malloc(conn->recv_buffer_size);  // ← NO CHECK!
conn->send_buffer_size = OBSWS_DEFAULT_BUFFER_SIZE;
conn->send_buffer = malloc(conn->send_buffer_size);  // ← NO CHECK!

Impact

If malloc fails (out of memory):

• recv_buffer or send_buffer will be NULL
• Later operations will dereference NULL → crash
• No graceful error handling

Note: Should also check the lws_context and wsi allocations later in the function for consistency.
