Last modified
CVE-2019-13648 is a vulnerability of currently unknown severity. In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c.. EPSS estimates a 0.59% chance of exploitation in the next 30 days.
