Name of the Vulnerable Software and Affected Versions GCC Toolset (affected versions not specified)

Description The issue concerns certain Intel CPUs affected by the Jump Conditional Code (JCC) bug, causing machine instructions to be executed incorrectly. This can lead to affected CPUs not executing programs properly. A workaround is available by recompiling programs using GCC with the -Wa,-mbranches-within-32B-boundaries command-line option, which helps mitigate performance loss but does not fully protect the system without a microcode update.

Recommendations To apply the workaround, recompile a program using GCC with the -Wa,-mbranches-within-32B-boundaries command-line option. Note that applying the workaround will increase the size of the program and there can still be a slight performance decrease. The full fix involves updating the microcode of vulnerable CPUs.
