We first learned about this information on Facebook in October 2023 and immediately began to investigate. Here&#8217;s what we found.<\/p>\n<p>&nbsp;<\/p>\n<h2>What is CVE-2022-32947, and How Did Asahi Lina Discover It?<\/h2>\n<p><iframe loading=\"lazy\" title=\"Did I just hack macOS??? \u3010Lina &amp; Cyan Nyan\u3011\" width=\"696\" height=\"392\" src=\"https:\/\/www.youtube.com\/embed\/ToulgVAofw8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/p>\n<p>In short, from the information we gathered from a video and a short statement by Asahi Lina, this vulnerability was discovered while Asahi Lina was livestreaming. At that time, she was experimenting with Apple&#8217;s GPU on MacOS, and she unintentionally realized that she could overwrite system memory, gaining root access.<\/p>\n<p>Without delay, she reported this bug or vulnerability to Apple Security and received a reward. Several months later, her name and username were officially included in the <strong>credits or Hall of Fame on the apple.com<\/strong> website for her discovery of a critical security vulnerability in MacOS, iOS, and other systems <a href=\"https:\/\/support.apple.com\/en-us\/HT213488\">https:\/\/support.apple.com\/en-us\/HT213488<\/a> .<\/p>\n<p>You can watch the full explanation and details of this vulnerability in a video livestream from one month ago <a href=\"https:\/\/asahilina.net\/agx-exploit\/\">here<\/a> or you can watch the video from this below:<\/p>\n<p>&nbsp;<\/p>\n<h2>Who Is Asahi Lina?<\/h2>\n<p>Asahi Lina, who goes by the username @LinaAsahi or @AsahiLina, is indeed known for regularly conducting live streams and uploading content on YouTube. Based on our observations, as of now, the YouTube channel @AsahiLina has reached approximately 23.1 thousand subscribers.<\/p>\n<p>Through our research, we also discovered that Asahi Lina is a developer and the creator of Asahi Linux OS. It&#8217;s no surprise that, upon visiting her YouTube channel, you&#8217;ll find that most of her video and livestream content revolves around app programming, Linux programming, assembly language, reverse engineering, and operating systems.<\/p>\n<p>The majority of her content delves into experiments in reverse engineering and discussions about programming applications\/machines in Apple software and hardware, such as MacOS.<\/p>\n<figure id=\"attachment_4072\" aria-describedby=\"caption-attachment-4072\" style=\"width: 696px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\" td-modal-image wp-image-4072 size-large\" src=\"https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-1024x576.png\" alt=\"Asahi Lina get Bounty Reward\" width=\"696\" height=\"392\" srcset=\"https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-1024x576.png 1024w, https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-300x169.png 300w, https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-768x432.png 768w, https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-1536x864.png 1536w, https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-150x84.png 150w, https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-696x392.png 696w, https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000-1068x601.png 1068w, https:\/\/secry.me\/explore\/wp-content\/uploads\/2023\/10\/Asahi-Lina-get-Bounty-USD-150000.png 1920w\" sizes=\"auto, (max-width: 696px) 100vw, 696px\" \/><figcaption id=\"caption-attachment-4072\" class=\"wp-caption-text\">Asahi Lina get Bounty USD 150000<\/figcaption><\/figure>\n<p>There is no exact information regarding the bug bounty reward amount from Apple for CVE-2022-32947, which Asahi Lina discovered.
