USN-5876-1: Linux kernel vulnerabilities It was discovered that a memory leak existed in the Unix domain socket implementation of the Linux kernel. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3543) It was discovered that the Bluetooth HCI implementation in the Linux kernel did not properly deallocate memory in some situations. An attacker could possibly use this cause a denial of service (memory exhaustion). (CVE-2022-3619) It was discovered that the hugetlb implementation in the Linux kernel contained a race condition in some situations. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2022-3623) 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 [ more… ]

USN-5875-1: Linux kernel (GKE) vulnerabilities It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43945) Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896) 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 [ more… ]

USN-5874-1: Linux kernel vulnerabilities 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 [ more… ]

USN-5872-1: NSS vulnerabilities Tavis Ormandy discovered that NSS incorrectly handled an empty pkcs7 sequence. A remote attacker could possibly use this issue to cause NSS to crash, resulting in a denial of service. (CVE-2022-22747) Ronald Crane discovered that NSS incorrectly handled certain memory operations. A remote attacker could use this issue to cause NSS to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2022-34480) Source: USN-5872-1: NSS vulnerabilities

USN-5870-1: apr-util vulnerability Ronald Crane discovered that APR-util did not properly handled memory when encoding or decoding certain input data. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. Source: USN-5870-1: apr-util vulnerability
