Moderate: kernel security update (Amazon Linux 2)

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2018-9363: A buffer overflow due to a singed-unsigned comparsion was found in hidp_process_report() in the net/bluetooth/hidp/core.c in the Linux kernel. The buffer length is an unsigned int but gets cast to a signed int which in certain conditions can lead to a system panic and a denial-of-service. 1623067: CVE-2018-9363 kernel: Buffer overflow in hidp_process_report CVE-2018-15594: It was found that paravirt_patch_call/jump() functions in the arch/x86/kernel/paravirt.c in the Linux kernel mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtualized guests. 1620555: CVE-2018-15594 kernel: Mishandling of indirect calls weakens Spectre mitigation for paravirtual guests
