| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2023-04-26 | CVE-2023-0458 | NULL Pointer Dereference vulnerability in multiple products A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. | 4.7 |
| 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 |
| 2023-04-25 | CVE-2023-2269 | Improper Locking vulnerability in multiple products A denial of service problem was found, due to a possible recursive locking scenario, resulting in a deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-component. | 4.4 |
| 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 |
| 2023-04-24 | CVE-2023-2019 | A flaw was found in the Linux kernel's netdevsim device driver, within the scheduling of events. | 4.4 |
| 2023-04-24 | CVE-2023-31081 | NULL Pointer Dereference vulnerability in Linux Kernel 6.2 An issue was discovered in drivers/media/test-drivers/vidtv/vidtv_bridge.c in the Linux kernel 6.2. | 5.5 |
