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 •

https://notcve.org/view.php?id=CVE-2023-2430
30 Jun 2023 — A vulnerability was found due to missing lock for IOPOLL flaw in io_cqring_event_overflow() in io_uring.c in Linux Kernel. This flaw allows a local attacker with user privilege to trigger a Denial of Service threat. Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. Xingyuan Mo and Gengjia Chen discovered that the io_uring subsystem in t... • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e12d7a46f65ae4b7d58a5e0c1cbfa825cf8 • CWE-413: Improper Resource Locking CWE-667: Improper Locking •
CVE-2023-1206 – kernel: hash collisions in the IPv6 connection lookup table
https://notcve.org/view.php?id=CVE-2023-1206
30 Jun 2023 — A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. 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. ... • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-400: Uncontrolled Resource Consumption •
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. Una vulnerabilidad de escritura fuera de los límites de la memoria en el controlador de red ipvlan del kernel de Linux se puede explotar p... • http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html • CWE-787: Out-of-bounds Write •
