A local attacker could use this to cause a \ndenial of service (system crash) or possibly execute arbitrary code. \n(CVE-2022-1679)\n\nYongkang Jia discovered that the KVM hypervisor implementation in the Linux \nkernel did not properly handle guest TLB mapping invalidation requests in \nsome situations. An attacker in a guest VM could use this to cause a denial \nof service (system crash) in the host OS. (CVE-2022-1789)\n\nQiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM hypervisor \nimplementation in the Linux kernel did not properly handle an illegal \ninstruction in a guest, resulting in a null pointer dereference. An \nattacker in a guest VM could use this to cause a denial of service (system \ncrash) in the host OS. (CVE-2022-1852)\n\nGerald Lee discovered that the NTFS file system implementation in the Linux \nkernel did not properly handle certain error conditions, leading to a use- \nafter-free vulnerability. A local attacker could use this to cause a denial \nof service (system crash) or possibly expose sensitive information. \n(CVE-2022-1973)\n\nIt was discovered that the netfilter subsystem in the Linux kernel \ncontained a buffer overflow in certain situations. A local attacker could \nuse this to cause a denial of service (system crash) or possibly execute \narbitrary code. (CVE-2022-2078)\n\nIt was discovered that some Intel processors did not completely perform \ncleanup actions on multi-core shared buffers. A local attacker could \npossibly use this to expose sensitive information. (CVE-2022-21123)\n\nIt was discovered that some Intel processors did not completely perform \ncleanup actions on microarchitectural fill buffers. A local attacker could \npossibly use this to expose sensitive information. (CVE-2022-21125)\n\nIt was discovered that some Intel processors did not properly perform \ncleanup during specific special register write operations. A local attacker \ncould possibly use this to expose sensitive information. (CVE-2022-21166)\n\nIt was discovered that the virtio RPMSG bus driver in the Linux kernel \ncontained a double-free vulnerability in certain error conditions. A local \nattacker could possibly use this to cause a denial of service (system \ncrash). (CVE-2022-34494, CVE-2022-34495)\n\nMinh Yuan discovered that the floppy disk driver in the Linux kernel \ncontained a race condition, leading to a use-after-free vulnerability.

"The version of kernel installed on the remote host is prior to 5.15.50-23.125. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-002 advisory.\n\n - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.\n (CVE-2022-1789)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal instruction in guest in the Intel CPU. (CVE-2022-1852)\n\n - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2022-32250. Reason: This candidate is a duplicate of CVE-2022-32250. Notes: All CVE users should reference CVE-2022-32250 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage. (CVE-2022-1966)\n\n - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code. (CVE-2022-2078)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point registers. (CVE-2022-32981)\n\n - rpmsg_virtio_add_ctrl_dev in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free. (CVE-2022-34494)\n\n - rpmsg_probe in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free.\n (CVE-2022-34495)\n\n - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel.

(CVE-2022-1966)\n\n - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code. (CVE-2022-2078)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point registers. (CVE-2022-32981)\n\n - rpmsg_virtio_add_ctrl_dev in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free. (CVE-2022-34494)\n\n - rpmsg_probe in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free.\n (CVE-2022-34495)\n\n - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494) (CVE-2022-1184)\n\n - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub- component.

This flaw allows a local attacker with a user privilege to cause a denial of service.\n (CVE-2022-1184)\n\n - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.\n (CVE-2022-1789)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal instruction in guest in the Intel CPU. (CVE-2022-1852)\n\n - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2022-32250. Reason: This candidate is a duplicate of CVE-2022-32250. Notes: All CVE users should reference CVE-2022-32250 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage. (CVE-2022-1966)\n\n - A use-after-free flaw was found in the Linux kernel in log_replay in fs/ntfs3/fslog.c in the NTFS journal.\n This flaw allows a local attacker to crash the system and leads to a kernel information leak problem.\n (CVE-2022-1973)\n\n - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code. (CVE-2022-2078)\n\n - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).\n Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point registers.
