CVE-2019-13648

Priority
Description
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.
Ubuntu-Description
Praveen Pandey discovered that the Linux kernel did not properly validate
sent signals in some situations on PowerPC systems with transactional
memory disabled. A local attacker could use this to cause a denial of
service.
