Summary: linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.19, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi vulnerabilities

Details: It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel contained 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-2023-1281) Lin Ma discovered a race condition in the io_uring subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-0468) It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3424) Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not properly perform reference counting 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-2022-41218) It was discovered that the network queuing discipline implementation in the Linux kernel contained a null pointer dereference in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-47929) Thadeu Cascardo discovered that the io_uring subsystem contained a double- free vulnerability in certain memory allocation error conditions. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-1032) It was discovered that the module decompression implementation in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-22997) Lianhui Tang discovered that the MPLS implementation in the Linux kernel did not properly handle certain sysctl allocation failure conditions, leading to a double-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2023-26545) It was discovered that the NTFS file system implementation in the Linux kernel did not properly handle a loop termination condition, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-26606) Wei Chen discovered that the DVB USB AZ6027 driver in the Linux kernel contained a null pointer dereference when handling certain messages from user space. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-28328)
