CVE-2019-13048
kernel/sys/syscall.c in ToaruOS through 1.10.9 allows a denial of service upon a critical error in certain sys_sbrk allocation patterns (involving PAGE_SIZE, and a value less than PAGE_SIZE).
Does this matter?
Lower severity and a low EPSS score (0.40%). Track it; it rarely justifies an emergency change on its own.
