(CVE-2022-0812)\n\nMoshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation \nin the Linux kernel did not provide sufficient randomization when \ncalculating port offsets. An attacker could possibly use this to expose \nsensitive information. (CVE-2022-1012, CVE-2022-32296)\n\nDuoming Zhou discovered that race conditions existed in the timer handling \nimplementation of the Linux kernel's Rose X.25 protocol layer, resulting in \nuse-after-free vulnerabilities. A local attacker could use this to cause a \ndenial of service (system crash). (CVE-2022-2318)\n\nRoger Pau Monn\u00e9 discovered that the Xen virtual block driver in the Linux \nkernel did not properly initialize memory pages to be used for shared \ncommunication with the backend. A local attacker could use this to expose \nsensitive information (guest kernel memory). (CVE-2022-26365)\n\nRoger Pau Monn\u00e9 discovered that the Xen paravirtualization frontend in the \nLinux kernel did not properly initialize memory pages to be used for shared \ncommunication with the backend. A local attacker could use this to expose \nsensitive information (guest kernel memory). (CVE-2022-33740)\n\nIt was discovered that the Xen paravirtualization frontend in the Linux \nkernel incorrectly shared unrelated data when communicating with certain \nbackends. A local attacker could use this to cause a denial of service \n(guest crash) or expose sensitive information (guest kernel memory). \n(CVE-2022-33741, CVE-2022-33742)\n\nOleksandr Tyshchenko discovered that the Xen paravirtualization platform in \nthe Linux kernel on ARM platforms contained a race condition in certain \nsituations. An attacker in a guest VM could use this to cause a denial of \nservice in the host OS.

(CVE-2022-33743)\n\n - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages. (CVE-2022-33744)\n\n - An issue was discovered in the Linux kernel through 5.18.9.

(CVE-2021-33655)\n\n - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that\n allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)\n\n - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text\n explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device\n 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\n unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend\n (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)\n\n - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data\n Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further\n processing to nevertheless be freed. (CVE-2022-33743)\n\n - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree\n to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the\n related lock held, resulting in a small race window, which can be used by unprivileged guests via PV\n devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS)\n of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory\n pages. (CVE-2022-33744)\n\n - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init\n (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different\n vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an\n unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data\n in net/netfilter/nf_tables_api.c.

Therefore its freeing may take more time than is reasonable without\n intermediate preemption checks. Such checking for the need to preempt was so far missing. (CVE-2022-33746)\n\n - lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was\n inserted on an error handling path. While doing so, locking requirements were not paid attention to. As a\n result two cooperating guests granting each other transitive grants can cause locks to be acquired nested\n within one another, but in respectively opposite order. With suitable timing between the involved grant\n copy operations this may result in the locking up of a CPU.

USN-5623-1 advisory.\n\n - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)\n\n - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. (CVE-2021-33655)\n\n - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. (CVE-2022-1012)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\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 - A flaw out of bounds memory write in the Linux kernel UDF file system functionality was found in the way user triggers some file operation which triggers udf_write_fi(). A local user could use this flaw to crash the system or potentially (CVE-2022-1943)\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 - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)\n\n - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)\n\n - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system. (CVE-2022-2873)\n\n - A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring().\n The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper locking when performing operations on an object. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-2959)\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 - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used. (CVE-2022-32296)\n\n - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further processing to nevertheless be freed. (CVE-2022-33743)\n\n - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages. (CVE-2022-33744)\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 - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.

(CVE-2021-33655)\n\n - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the\n small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of\n service problem. (CVE-2022-1012)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged\n user to gain root privileges. The bug allows to build several exploit primitives such as kernel address\n information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of\n service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal\n instruction in guest in the Intel CPU. (CVE-2022-1852)\n\n - A flaw out of bounds memory write in the Linux kernel UDF file system functionality was found in the way\n user triggers some file operation which triggers udf_write_fi(). A local user could use this flaw to crash\n the system or potentially (CVE-2022-1943)\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 - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that\n allow attackers to crash linux kernel without any privileges.

Device-mapper table reloads currently\n allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass\n verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and\n unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for\n peripherals that do not verify firmware updates.

This flaw allows a local user to crash the system. (CVE-2022-2873)\n\n - A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring().\n The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper\n locking when performing operations on an object. This flaw allows a local user to crash the system or\n escalate their privileges on the system.

(CVE-2022-32296)\n\n - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data\n Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further\n processing to nevertheless be freed. (CVE-2022-33743)\n\n - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree\n to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the\n related lock held, resulting in a small race window, which can be used by unprivileged guests via PV\n devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS)\n of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory\n pages.
