| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-09-12 | CVE-2023-4921 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in agg_dequeue(). We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. | 7.8 |
| 2023-09-06 | CVE-2023-4206 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to achieve local privilege escalation. When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. | 7.8 |
| 2023-09-06 | CVE-2023-4207 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. When fw_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. | 7.8 |
| 2023-09-06 | CVE-2023-4208 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. When u32_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. | 7.8 |
| 2023-09-06 | CVE-2023-4244 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability. We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8. | 7.0 |
| 2023-09-06 | CVE-2023-4622 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. | 7.0 |
| 2023-09-06 | CVE-2023-4623 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. | 7.8 |
| 2023-08-29 | CVE-2023-4611 | Use After Free vulnerability in Linux Kernel A use-after-free flaw was found in mm/mempolicy.c in the memory management subsystem in the Linux Kernel. | 6.3 |
| 2023-08-28 | CVE-2023-4569 | Memory Leak vulnerability in multiple products A memory leak flaw was found in nft_set_catchall_flush in net/netfilter/nf_tables_api.c in the Linux Kernel. | 5.5 |
| 2023-08-17 | CVE-2023-4394 | Use After Free vulnerability in Linux Kernel A use-after-free flaw was found in btrfs_get_dev_args_from_path in fs/btrfs/volumes.c in btrfs file-system in the Linux Kernel. | 6.0 |
