USN-6318-1: Linux kernel vulnerabilities
First published: Tue Aug 29 2023(Updated: )
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) Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information. (CVE-2023-20593) It was discovered that the universal 32bit network packet classifier implementation 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-2023-3609) It was discovered that the netfilter subsystem in the Linux kernel did not properly handle certain error 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-2023-3610) It was discovered that the Quick Fair Queueing network scheduler implementation in the Linux kernel contained 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-2023-3611) It was discovered that the network packet classifier with netfilter/firewall marks implementation in the Linux kernel did not properly handle reference counting, 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-2023-3776) Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle table rules flush in certain circumstances. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-3777) Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle rule additions to bound chains in certain circumstances. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-3995) It was discovered that the netfilter subsystem in the Linux kernel did not properly handle PIPAPO element removal, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-4004) Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle bound chain deactivation in certain circumstances. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-4015)
