That's not a "bad sector". This is a "bad sector":

Jan 29 07:41:01 xxx kernel: [5687751.356991] sd 0:x:x:x: [sdx] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE

And you can easily tell one from another. Yours is saying "timeout".
Mine's saying "critical medium error".

What you're seeing is your drive's firmware is hanging on processing a
certain SCSI command. Could be the drive itself, its firmware, or (as
other helpfully suggested) - the SATA cable,

To answer your question - Linux can handle bad sectors just fine. It's
the failing hardware (especially consumer-quality failing hardware) that
it has difficulties with.
