USN-5560-1: Linux kernel vulnerabilities

First published: Wed Aug 10 2022(Updated: )

Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2588) It was discovered that the netfilter subsystem of the Linux kernel did not prevent one nft object from referencing an nft set in another nft table, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2586) It was discovered that the block layer subsystem in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0494) Hu Jiahui discovered that multiple race conditions existed in the Advanced Linux Sound Architecture (ALSA) framework, leading to use-after-free vulnerabilities. A local attacker could use these to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1048) It was discovered that the implementation of the 6pack and mkiss protocols in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1195) Minh Yuan discovered that the floppy disk driver in the Linux kernel contained a race condition, 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-2022-1652) It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some 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-2022-1679) Norbert Slusarek discovered that a race condition existed in the perf subsystem in the Linux kernel, resulting in a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1729) It was discovered that the Marvell NFC device driver implementation in the Linux kernel did not properly perform memory cleanup operations in some situations, 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-2022-1734) Duoming Zhou discovered a race condition in the NFC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1974) Duoming Zhou discovered that the NFC subsystem in the Linux kernel did not properly prevent context switches from occurring during certain atomic context operations. A privileged local attacker could use this to cause a denial of service (system crash). (CVE-2022-1975) Minh Yuan discovered that the floppy driver 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-2022-33981) Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel did not properly perform data validation. A local attacker could use this to escalate privileges in certain situations. (CVE-2022-34918)
