5) Out-of-bounds read

EUVDB-ID: #VU80795

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-37453

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows an attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the read_descriptors() function in drivers/usb/core/sysfs.c. An attacker with physical access to the system can attach a malicious USB device, trigger an out-of-bounds read error and crash the kernel.

Mitigation

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

8) Use-after-free

EUVDB-ID: #VU79486

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

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.

11) Use-after-free

EUVDB-ID: #VU79713

Risk: Low

CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2023-4147

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

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

The vulnerability exists due to a use-after-free error in Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. 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.

13) Stack-based buffer overflow

EUVDB-ID: #VU79487

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-4273

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in the implementation of the file name reconstruction function in the exFAT driver in Linux kernel. A local user can trigger a stack overflow and execute arbitrary code with elevated privileges.

Mitigation

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

14) Double Free

EUVDB-ID: #VU80796

Risk: Low

CVSSv4.0: 4.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

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
