A local unprivileged user could use this to obtain to\nsensitive information. (CVE-2022-40982)\n\nYang Lan discovered that the GFS2 file system implementation in the Linux\nkernel could attempt to dereference a null pointer in some situations. An\nattacker could use this to construct a malicious GFS2 image that, when\nmounted and operated on, could cause a denial of service (system crash).\n(CVE-2023-3212)\n\nIt was discovered that the NET/ROM protocol implementation in the Linux\nkernel contained a race condition in some situations, leading to a use-\nafter-free vulnerability. A local attacker could use this to cause a denial\nof service (system crash) or possibly execute arbitrary code.\n(CVE-2023-32269)\n\nIt was discovered that the NFC implementation in the Linux kernel contained\na use-after-free vulnerability when performing peer-to-peer communication\nin certain conditions. A privileged attacker could use this to cause a\ndenial of service (system crash) or possibly expose sensitive information\n(kernel memory). (CVE-2023-3863)\n\nIt was discovered that the bluetooth subsystem in the Linux kernel did not\nproperly handle L2CAP socket release, leading to a use-after-free\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-40283)\n\nIt was discovered that some network classifier implementations in the Linux\nkernel contained use-after-free vulnerabilities. A local attacker could use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2023-4128)\n\nIt was discovered that the JFS file system implementation in the Linux\nkernel did not properly validate memory allocations in certain situations,\nleading to a null pointer dereference vulnerability. An attacker could use\nthis to construct a malicious JFS image that, when mounted, could cause a\ndenial of service (system crash). (CVE-2023-4385)\n\nIt was discovered that the VMware VMXNET3 ethernet driver in the Linux\nkernel contained a use-after-free vulnerability in certain situations. A\nlocal attacker in a guest VM could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-4387)\n\nIt was discovered that the VMware VMXNET3 ethernet driver in the Linux\nkernel did not properly handle errors in certain situations, leading to a\nnull pointer dereference vulnerability. A local attacker in a guest VM\ncould use this to cause a denial of service (system crash).
