2) Use-after-free

EUVDB-ID: #VU80794

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-40133

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the vmw_execbuf_tie_context() function in drivers/gpu/vmxgfx/vmxgfx_execbuf.c. A local user can run a specially crafted program on the system and perform a denial of service (DoS) attack.

4) Use-after-free

EUVDB-ID: #VU75769

Risk: Medium

CVSSv3.1: 6.6 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-1859

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a malicious guest to gain access to sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the xen_9pfs_front_removet() function in net/9p/trans_xen.c in Xen transport for 9pfs. A malicious guest VM can trigger a use-after-free error and gain access to sensitive information of the hypervisor or crash it.

Mitigation

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

9) Use-after-free

EUVDB-ID: #VU78779

Risk: Low

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3610

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 nf_tables component in Linux kernel netfilter. A local user with CAP_NET_ADMIN capability 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.

10) Out-of-bounds read

EUVDB-ID: #VU80795

Risk: Low

CVSSv3.1: 4 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

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.

14) Use-after-free

EUVDB-ID: #VU79486

Risk: Low

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.

The vulnerability exists due to a use-after-free error within the nft_verdict_dump() function of the nftables sub-component. A local user can trigger a race condition between set GC and transaction and perform a DoS attack.

Mitigation

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