Daniel Moghimi discovered that some Intel(R) Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensitive information. (CVE-2022-40982)
Yang Lan discovered that the GFS2 file system implementation in the Linux kernel could attempt to dereference a null pointer in some situations. An attacker could use this to construct a malicious GFS2 image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2023-3212)
It was discovered that the NET/ROM protocol implementation in the Linux kernel contained a race condition in some situations, 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-2023-32269)
It was discovered that the NFC implementation in the Linux kernel contained a use-after-free vulnerability when performing peer-to-peer communication in certain conditions. A privileged attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2023-3863)
It was discovered that the bluetooth subsystem in the Linux kernel did not properly handle L2CAP socket release, 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-2023-40283)
It was discovered that some network classifier implementations in the Linux kernel contained use-after-free vulnerabilities. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4128)
It was discovered that the JFS file system implementation in the Linux kernel did not properly validate memory allocations in certain situations, leading to a null pointer dereference vulnerability. An attacker could use this to construct a malicious JFS image that, when mounted, could cause a denial of service (system crash). (CVE-2023-4385)
It was discovered that the VMware VMXNET3 ethernet driver in the Linux kernel contained a use-after-free vulnerability in certain situations. A local attacker in a guest VM could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4387)
It was discovered that the VMware VMXNET3 ethernet driver in the Linux kernel did not properly handle errors in certain situations, leading to a null pointer dereference vulnerability. A local attacker in a guest VM could use this to cause a denial of service (system crash). (CVE-2023-4459)
