| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-06-05 | CVE-2023-3111 | Use After Free vulnerability in multiple products A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the Linux Kernel. | 7.8 |
| 2023-06-01 | CVE-2023-2598 | Out-of-bounds Write vulnerability in multiple products 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. | 7.8 |
| 2023-05-31 | CVE-2022-48502 | Out-of-bounds Read vulnerability in multiple products An issue was discovered in the Linux kernel before 6.2. | 7.1 |
| 2023-05-15 | CVE-2023-2124 | Out-of-bounds Write vulnerability in multiple products An out-of-bounds memory access flaw was found in the Linux kernel’s XFS file system in how a user restores an XFS image after failure (with a dirty log journal). | 7.8 |
| 2023-05-09 | CVE-2023-2156 | Reachable Assertion vulnerability in multiple products A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. | 7.5 |
| 2023-05-08 | CVE-2023-32233 | Use After Free vulnerability in multiple products In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. | 7.8 |
| 2023-05-01 | CVE-2023-2235 | Use After Free vulnerability in Linux Kernel A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2. | 7.8 |
| 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 |
