CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3772

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the xfrm_update_ae_params() function in the IP framework for transforming packets (XFRM subsystem). A local user with CAP_NET_ADMIN privileges can perform a denial of service (DoS) attack.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVSSv3.1: 7.1 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3863

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the nfc_llcp_find_local() function in net/nfc/llcp_core.c in NFC implementation in Linux kernel. A local user can execute arbitrary code with elevated privileges.


Mitigation

Update the affected package the Linux Kernel to the latest version.

CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4128

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in the Linux Kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4387

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to a boundary error within the vmxnet3_rq_alloc_rx_buf() function in drivers/net/vmxnet3/vmxnet3_drv.c in VMware vmxnet3 ethernet NIC driver. A local user can  trigger a double free error and gain access to sensitive information or crash the kernel.

Mitigation

Update the affected package the Linux Kernel to the latest version.
