It was discovered that a race condition existed in the ATM (Asynchronous Transfer Mode) subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-51780) It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-51781) It was discovered that a race condition existed in the Rose X.25 protocol implementation in the Linux kernel, leading to a use-after- free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-51782) Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker could use this to expose sensitive information (kernel memory). (CVE-2023-6121) Jann Horn discovered that a race condition existed in the Linux kernel when handling iouring over sockets, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-6531) Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle dynset expressions passed from userspace, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-6622) It was discovered that the IGMP protocol implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-6932) Robert Morris discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain server commands fields, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-0565) Dan Carpenter discovered that the netfilter subsystem in the Linux kernel did not store data in properly sized memory locations. A local user could use this to cause a denial of service (system crash). (CVE-2024-0607) Jann Horn discovered that the TLS subsystem in the Linux kernel did not properly handle spliced messages, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-0646) Yang Chaoming discovered that the KSMBD implementation in the Linux kernel did not properly validate request buffer sizes, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-22705)
