| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-10-03 | CVE-2023-5345 | Use After Free vulnerability in multiple products A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free. We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705. | 7.8 |
| 2023-09-28 | CVE-2023-42756 | Race Condition vulnerability in multiple products A flaw was found in the Netfilter subsystem of the Linux kernel. | 4.7 |
| 2023-09-27 | CVE-2023-5197 | Use After Free vulnerability in Linux Kernel A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free. We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325. | 6.6 |
| 2023-09-25 | CVE-2023-42753 | Out-of-bounds Write vulnerability in multiple products An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. | 7.8 |
| 2023-09-22 | CVE-2023-34319 | Out-of-bounds Write vulnerability in multiple products The fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a way such that not all of the headers would come in one piece. | 7.8 |
| 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 |
