| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-01-30 | CVE-2023-0240 | Use After Free vulnerability in Linux Kernel There is a logic error in io_uring's implementation which can be used to trigger a use-after-free vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the last io_grab_identity call cannot return false is not true, and in this case the function will use the init_cred or the previous linked requests identity to do operations instead of using the current identity. | 7.8 |
| 2023-01-26 | CVE-2023-0394 | NULL Pointer Dereference vulnerability in Linux Kernel A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network subcomponent in the Linux kernel. | 5.5 |
| 2023-01-26 | CVE-2023-0468 | Use After Free vulnerability in Linux Kernel A use-after-free flaw was found in io_uring/poll.c in io_poll_check_events in the io_uring subcomponent in the Linux Kernel due to a race condition of poll_refs. | 4.7 |
| 2023-01-26 | CVE-2023-0469 | Use After Free vulnerability in Linux Kernel A use-after-free flaw was found in io_uring/filetable.c in io_install_fixed_file in the io_uring subcomponent in the Linux Kernel during call cleanup. | 5.5 |
| 2023-01-17 | CVE-2022-47929 | NULL Pointer Dereference vulnerability in multiple products In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. | 5.5 |
| 2022-12-07 | CVE-2022-42328 | Improper Locking vulnerability in multiple products Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the XSA-392 handling (CVE-2022-42328). | 5.5 |

| 2022-11-30 | CVE-2022-45869 | Race Condition vulnerability in Linux Kernel A race condition in the x86 KVM subsystem in the Linux kernel through 6.1-rc6 allows guest OS users to cause a denial of service (host OS crash or host OS memory corruption) when nested virtualisation and the TDP MMU are enabled. | 5.5 |
| 2022-11-28 | CVE-2022-4127 | NULL Pointer Dereference vulnerability in Linux Kernel A NULL pointer dereference issue was discovered in the Linux kernel in io_files_update_with_index_alloc. | 5.5 |
| 2022-11-25 | CVE-2022-45884 | Use After Free vulnerability in multiple products An issue was discovered in the Linux kernel through 6.0.9. | 7.0 |
