The first vulnerability (CVE-2019-5614) can lead to access to memory outside the allocated mbuf buffer when processing specially crafted TCP packets, while the second (CVE-2019-15874) can result in access to already freed memory areas (use-after-free). <\/p>\n<p>An analysis of the suitability of the identified issues for exploitation capable of initiating the execution of malicious code has not been conducted, but it cannot be ruled out that the vulnerabilities may extend beyond just causing kernel crashes.

revealed that these fixes are related to resolving vulnerabilities).<\/p>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Fonte: <a \ncontent=\"nofollow\" rel=\"nofollow\"
