Summary
linux-azure, linux-azure-5.15, linux-azure-fde, linux-azure-fde-5.15 vulnerabilities
Details

Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32250, CVE-2023-32252, CVE-2023-32257)

Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service (paravirtualized device unavailability). (CVE-2023-34324)

Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during device removal. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-35827)

Tom Dohrmann discovered that the Secure Encrypted Virtualization (SEV) implementation for AMD processors in the Linux kernel contained a race condition when accessing MMIO registers. A local attacker in a SEV guest VM could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-46813)

It was discovered that the Microchip USB Ethernet driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-6039)

It was discovered that the TLS subsystem in the Linux kernel did not properly perform cryptographic operations in some situations, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-6176)

Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle dynset expressions passed from userspace, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-6622)

It was discovered that the TIPC protocol implementation in the Linux kernel did not properly handle locking during tipc_crypto_key_revoke() operations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2024-0641)

(CVE-2023-32250, CVE-2023-32252,\nCVE-2023-32257)\n\nMarek Marczykowski-G\u00f3recki discovered that the Xen event channel\ninfrastructure implementation in the Linux kernel contained a race\ncondition. An attacker in a guest VM could possibly use this to cause a\ndenial of service (paravirtualized device unavailability). (CVE-2023-34324)\n\nZheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver\nin the Linux kernel during device removal. A privileged attacker could use\nthis to cause a denial of service (system crash). (CVE-2023-35827)\n\nTom Dohrmann discovered that the Secure Encrypted Virtualization (SEV)\nimplementation for AMD processors in the Linux kernel contained a race\ncondition when accessing MMIO registers. A local attacker in a SEV guest VM\ncould possibly use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-46813)\n\nIt was discovered that the Microchip USB Ethernet driver in the Linux\nkernel contained a race condition during device removal, leading to a use-\nafter-free vulnerability. A physically proximate attacker could use this to\ncause a denial of service (system crash). (CVE-2023-6039)\n\nIt was discovered that the TLS subsystem in the Linux kernel did not\nproperly perform cryptographic operations in some situations, leading to a\nnull pointer dereference vulnerability. A local attacker could use this to\ncause a denial of service (system crash) or possibly execute arbitrary\ncode. (CVE-2023-6176)\n\nXingyuan Mo discovered that the netfilter subsystem in the Linux kernel did\nnot properly handle dynset expressions passed from userspace, leading to a\nnull pointer dereference vulnerability. A local attacker could use this to\ncause a denial of service (system crash). (CVE-2023-6622)\n\nIt was discovered that the TIPC protocol implementation in the Linux kernel\ndid not properly handle locking during tipc_crypto_key_revoke() operations.\nA local attacker could use this to cause a denial of service (kernel\ndeadlock).
