It was discovered that the Layer 2 Tunneling Protocol (L2TP) implementation in the Linux kernel contained a race condition when releasing PPPoL2TP sockets in certain conditions, 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-2022-20567)
It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle block device modification while it is mounted. A privileged attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-34256)
Eric Dumazet discovered that the netfilter subsystem in the Linux kernel did not properly handle DCCP conntrack buffers in certain situations, leading to an out-of-bounds read vulnerability. An attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2023-39197)
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 the ext4 file system implementation in the Linux kernel did not properly handle the remount operation in certain cases, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-0775)
Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, 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-2024-1086)
It was discovered that a race condition existed in the SCSI Emulex LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF and re-scanning an HBA FCF table, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-24855)
