kernel is vulnerable to denial of service. The vulnerability exists as a missing validation check was found in the Linux kernel’s signals implementation. A local, unprivileged user could use this flaw to send signals via the sigqueueinfo system call, with the si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. Note: This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so.
