| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-05-01 | CVE-2023-2236 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Both io_install_fixed_file and its callers call fput in a file in case of an error, causing a reference underflow which leads to a use-after-free vulnerability. We recommend upgrading past commit 9d94c04c0db024922e886c9fd429659f22f48ea4. | 7.8 |
| 2023-04-28 | CVE-2023-31436 | Out-of-bounds Write vulnerability in Linux Kernel 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. | 7.8 |
| 2023-04-25 | CVE-2023-0045 | Externally Controlled Reference to a Resource in Another Sphere vulnerability in multiple products The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. | 7.5 |
| 2023-04-24 | CVE-2023-2007 | Improper Locking vulnerability in multiple products The specific flaw exists within the DPT I2O Controller driver. | 7.8 |
| 2023-04-24 | CVE-2023-2006 | Race Condition vulnerability in multiple products A race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC bundles. | 7.0 |
| 2023-04-20 | CVE-2023-2176 | Out-of-bounds Read vulnerability in Linux Kernel A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. | 7.8 |
| 2023-04-14 | CVE-2023-2008 | Improper Validation of Array Index vulnerability in Linux Kernel A flaw was found in the Linux kernel's udmabuf device driver. | 7.8 |
| 2023-04-12 | CVE-2023-1872 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local privilege escalation. The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered. We recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8. | 7.0 |
| 2023-04-12 | CVE-2023-1829 | Use After Free vulnerability in Linux Kernel 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 structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. | 7.8 |
| 2023-04-11 | CVE-2023-1989 | Use After Free vulnerability in multiple products A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. | 7.0 |
