Linux ia64 kernels have a floating point leak because the context switch code checks just the psr.mfh bit and doesn't look at who the FPH owner is. This allows a malicious program to set the MFH bit and look at the registers of another possibly sensitive process. Patch available and committed: http://lia64.bkbits.net:8080/to-linus-2.5/cset@1.1726.29.7 CAN-2004-0565 Affects: 3AS 3ES 3WS
