| CVE-2023-3389 | Hig | 0.51 | 7.8 | 0.01 | Jun 28, 2023 | A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit… | ||
| CVE-2023-35788 | Hig | 0.51 | 7.8 | 0.01 | Jun 16, 2023 | An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation. | ||
| CVE-2023-3111 | Hig | 0.51 | 7.8 | 0.00 | Jun 5, 2023 | A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling btrfs_ioctl_defrag(). | ||
| CVE-2023-2598 | Hig | 0.51 | 7.8 | 0.01 | Jun 1, 2023 | A flaw was found in the fixed buffer registration code for io_uring (io_sqe_buffer_register in io_uring/rsrc.c) in the Linux kernel that allows out-of-bounds access to physical memory beyond the end of the buffer. This flaw enables full local privilege escalation. | ||

| CVE-2023-31436 | Hig | 0.51 | 7.8 | 0.01 | Apr 28, 2023 | qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX. | ||
| CVE-2023-2176 | Hig | 0.51 | 7.8 | 0.00 | Apr 20, 2023 | A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem to crash the system or escalation of privilege. | ||
| CVE-2023-1829 | Hig | 0.51 | 7.8 | 0.01 | Apr 12, 2023 | A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying… | ||
| CVE-2023-28464 | Hig | 0.51 | 7.8 | 0.00 | Mar 31, 2023 | hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free that may lead to privilege escalation. | ||
| CVE-2023-1670 | Hig | 0.51 | 7.8 | 0.00 | Mar 30, 2023 | A flaw use after free in the Linux kernel Xircom 16-bit PCMCIA (PC-card) Ethernet driver was found.A local user could use this flaw to crash the system or potentially escalate their privileges on the system. | ||

The rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user can trigger this with rds_message_put(). Type confusion leads to `struct… | ||
| CVE-2023-1252 | Hig | 0.51 | 7.8 | 0.00 | Mar 23, 2023 | A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch… | ||
| CVE-2022-4095 | Hig | 0.51 | 7.8 | 0.00 | Mar 22, 2023 | A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and gain escalation of privileges. | ||
| CVE-2023-1281 | Hig | 0.51 | 7.8 | 0.00 | Mar 22, 2023 | Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation.

| CVE-2022-48424 | Hig | 0.51 | 7.8 | 0.00 | Mar 19, 2023 | In the Linux kernel before 6.1.3, fs/ntfs3/inode.c does not validate the attribute name offset. An unhandled page fault may occur. | ||
| CVE-2022-48423 | Hig | 0.51 | 7.8 | 0.00 | Mar 19, 2023 | In the Linux kernel before 6.1.3, fs/ntfs3/record.c does not validate resident attribute names. An out-of-bounds write may occur. | ||
| CVE-2022-3424 | Hig | 0.51 | 7.8 | 0.00 | Mar 6, 2023 | A use-after-free flaw was found in the Linux kernel’s SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially… | ||
| CVE-2023-22995 | Hig | 0.51 | 7.8 | 0.00 | Feb 28, 2023 | In the Linux kernel before 5.17, an error path in dwc3_qcom_acpi_register_core in drivers/usb/dwc3/dwc3-qcom.c lacks certain platform_device_put and kfree calls. |
