The vulnerability allows a local attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the "arch/powerpc/kernel/signal_32.c" and "arch/powerpc/kernel/signal_64.c" files on the PowerPC platform, when hardware transactional memory is disabled. A local authenticated attacker can make a "sigreturn()" system call that sends a signal frame that sends a signal frame that submits malicious input to the targeted system and cause a denial of service condition.
