{"id":"USN-5927-1","summary":"linux-azure-4.15 vulnerabilities","details":"It was discovered that the Upper Level Protocol (ULP) subsystem in the\nLinux kernel did not properly handle sockets entering the LISTEN state in\ncertain protocols, leading to a use-after-free vulnerability. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-0461)\n\nIt was discovered that the System V IPC implementation in the Linux kernel\ndid not properly handle large shared memory counts. A local attacker could\nuse this to cause a denial of service (memory exhaustion). (CVE-2021-3669)\n\nIt was discovered that a use-after-free vulnerability existed in the SGI\nGRU driver in the Linux kernel. A local attacker could possibly use this to\ncause a denial of service (system crash) or possibly execute arbitrary\ncode. (CVE-2022-3424)\n\nIt was discovered that a race condition existed in the Kernel Connection\nMultiplexor (KCM) socket implementation in the Linux kernel when releasing\nsockets in certain situations.

(CVE-2022-3640)\n\nHyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not\nproperly perform reference counting in some situations, leading to a use-\nafter-free vulnerability. A local attacker could use this to cause a denial\nof service (system crash) or possibly execute arbitrary code.\n(CVE-2022-41218)\n\nIt was discovered that a race condition existed in the Xen network backend\ndriver in the Linux kernel when handling dropped packets in certain\ncircumstances. An attacker could use this to cause a denial of service\n(kernel deadlock). (CVE-2022-42328, CVE-2022-42329)\n\nTamás Koczka discovered that the Bluetooth L2CAP implementation in the\nLinux kernel did not properly initialize memory in some situations. A\nphysically proximate attacker could possibly use this to expose sensitive\ninformation (kernel memory). (CVE-2022-42895)\n\nIt was discovered that the network queuing discipline implementation in the\nLinux kernel contained a null pointer dereference in some situations. A\nlocal attacker could use this to cause a denial of service (system crash).\n(CVE-2022-47929)\n\nJosé Oliveira and Rodrigo Branco discovered that the prctl syscall\nimplementation in the Linux kernel did not properly protect against\nindirect branch prediction attacks in some situations. A local attacker\ncould possibly use this to expose sensitive information. (CVE-2023-0045)\n\nIt was discovered that a use-after-free vulnerability existed in the\nAdvanced Linux Sound Architecture (ALSA) subsystem. A local attacker could\nuse this to cause a denial of service (system crash). (CVE-2023-0266)\n\nKyle Zeng discovered that the IPv6 implementation in the Linux kernel\ncontained a NULL pointer dereference vulnerability in certain situations. A\nlocal attacker could use this to cause a denial of service (system crash).\n(CVE-2023-0394)\n\nKyle Zeng discovered that the ATM VC queuing discipline implementation in\nthe Linux kernel contained a type confusion vulnerability in some\nsituations. An attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-23455)\n\nIt was discovered that the RNDIS USB driver in the Linux kernel contained\nan integer overflow vulnerability. A local attacker with physical access\ncould plug in a malicious USB device to cause a denial of service (system\ncrash) or possibly execute arbitrary code.
