USN-5874-1

Summary: linux-aws-5.4, linux-gcp, linux-gcp-5.4, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-oracle-5.4 vulnerabilities

Details: It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform bounds checking in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3628) It was discovered that a use-after-free vulnerability existed in the Bluetooth stack in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3640) Khalid Masum discovered that the NILFS2 file system implementation 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 or possibly execute arbitrary code. (CVE-2022-3649) It was discovered that a race condition existed in the SMSC UFX USB driver implementation in the Linux kernel, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41849) It was discovered that a race condition existed in the Roccat HID driver in the Linux kernel, 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-2022-41850) Tamás Koczka discovered that the Bluetooth L2CAP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-42895) It was discovered that the binder IPC implementation in the Linux kernel contained 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-2023-20928)
