CVE-2023-3338 – Crash due to a null pointer dereference in the dn_nsp_send function
https://notcve.org/view.php?id=CVE-2023-3338
30 Jun 2023 — A null pointer dereference flaw was found in the Linux kernel's DECnet networking protocol. This issue could allow a remote user to crash the system. It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. Daniël Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorise... • https://github.com/TurtleARM/CVE-2023-3338-DECPwn • CWE-476: NULL Pointer Dereference •
CVE-2023-3390 – Use-after-free in Linux kernel's netfilter subsystem
https://notcve.org/view.php?id=CVE-2023-3390
28 Jun 2023 — A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.

CVE-2023-3090 – Out-of-bounds write in Linux kernel's ipvlan network driver
https://notcve.org/view.php?id=CVE-2023-3090
28 Jun 2023 — 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 reachable if CONFIG_IPVLAN is enabled. We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e.
