{"id":"USN-6386-2","summary":"linux-raspi vulnerabilities","details":"Jana Hofmann, Emanuele Vannacci, Cedric Fournet, Boris Kopf, and Oleksii\nOleksenko discovered that some AMD processors could leak stale data from\ndivision operations in certain situations. A local attacker could possibly\nuse this to expose sensitive information. (CVE-2023-20588)\n\nIt was discovered that the bluetooth subsystem in the Linux kernel did not\nproperly handle L2CAP socket release, leading to a use-after-free\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-40283)\n\nIt was discovered that some network classifier implementations in the Linux\nkernel contained use-after-free vulnerabilities. A local attacker could use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2023-4128)\n\nLonial Con discovered that the netfilter subsystem in the Linux kernel\ncontained a memory leak when handling certain element flush operations. A\nlocal attacker could use this to expose sensitive information (kernel\nmemory).
