High 7.8
Out-of-bounds write in Linux kernel's ipvlan network driver
A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is r…

High 7.8CVE-2023-35001 Public exploit
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace
-
High 7.8CVE-2023-35788 Public exploit
An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an o…

High 7.8CVE-2023-3776 Public exploit
Use-after-free in Linux kernel's net/sched: cls_fw component
A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the refere…

Kernel: netfilter: use-after-free due to improper element removal in nft_pipapo_remove()
A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their pr…
