| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-09-06 | CVE-2023-4015 | 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. On an error when building a nftables rule, deactivating immediate expressions in nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but later used. We recommend upgrading past commit 0a771f7b266b02d262900c75f1e175c7fe76fec2. | 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 |
| 2023-08-21 | CVE-2023-4459 | NULL Pointer Dereference vulnerability in multiple products A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in the networking sub-component in vmxnet3 in the Linux Kernel. | 5.5 |
