USN-5566-1: 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 implementation of POSIX timers in the Linux kernel did not properly clean up timers in some situations. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2585) 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) Felix Fu discovered that the Sun RPC implementation in the Linux kernel did not properly handle socket states, leading to a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-28893) Johannes Wikner and Kaveh Razavi discovered that for some AMD x86-64 processors, the branch predictor could by mis-trained for return instructions in certain circumstances. A local attacker could possibly use this to expose sensitive information. (CVE-2022-29900) Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64 processors, the Linux kernel's protections against speculative branch target injection attacks were insufficient in some circumstances. A local attacker could possibly use this to expose sensitive information. (CVE-2022-29901) 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)
