Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-confusion error. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-12351) Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate remote attacker could use this to expose sensitive information (kernel memory). (CVE-2020-12352) Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490) Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-36402) Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during device removal. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-35827) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - GPU drivers; - I2C subsystem; - Network drivers; - Pin controllers subsystem; - TTY drivers; - USB Mass Storage drivers; - Framebuffer layer; - Ext4 file system; - File systems infrastructure; - Bluetooth subsystem; - Kernel init infrastructure; - DMA mapping infrastructure; - Memory management; - 9P file system network protocol; - IPv4 networking; - IPv6 networking; - Logical Link layer; - MAC80211 subsystem; - Netfilter; - NFC subsystem; - Phonet protocol; - Network traffic control; - Wireless networking; (CVE-2024-44947, CVE-2023-52594, CVE-2024-35886, CVE-2024-38633, CVE-2023-52509, CVE-2024-26625, CVE-2024-36946, CVE-2024-45021, CVE-2024-36270, CVE-2021-47118, CVE-2024-43884, CVE-2024-36941, CVE-2024-38619, CVE-2021-47501, CVE-2024-49967, CVE-2024-42090, CVE-2024-40912, CVE-2024-36968, CVE-2024-53057, CVE-2023-52507, CVE-2024-42101, CVE-2021-47086, CVE-2024-42153, CVE-2024-40959, CVE-2024-26777, CVE-2024-44944, CVE-2024-43856, CVE-2024-39301)

About

Kenya Education Network CERT(KENET-CERT) is a Cybersecurity Emergency Response Team and Co-ordination Center operated by the National Research and Education Network of Kenya. KENET-CERT coordination center promotes awareness on cybersecurity incidences as well as coordinates and assists member institutions in responding effectively to cyber security threats and incidences. KENET-CERT works closely with Kenya's National CIRT coordination center (CIRT/CC) as a sector CIRT for the academic institutions. KENET promotes use of ICT in Teaching, Learning and Research in Higher Education Institutions in Kenya. KENET aims to interconnect all the Universities, Tertiary and Research Institutions in Kenya by setting up a cost effective and sustainable private network with high speed access to the global Internet. KENET also facilitates electronic communication among students and faculties in member institutions, share learning and teaching resources by collaboration in Research and Development of Educational content.
