CVE-2024-58016
In the Linux kernel, the following vulnerability has been resolved: safesetid: check size of policy writes syzbot attempts to write a buffer with a large size to a sysfs entry with writes handled by handle_policy_update(), triggering a warning in kmalloc.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
