USN-5390-2

Summary: linux-raspi vulnerabilities

Details: David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-1015) David Bouman discovered that the netfilter subsystem in the Linux kernel did not initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-1016) It was discovered that the ST21NFCA NFC driver in the Linux kernel did not properly validate the size of certain data in EVT_TRANSACTION events. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-26490)
