2) Use-after-free

EUVDB-ID: #VU81923

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-1192

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 smb2_is_status_io_timeout() function in Linux kernel. A local user can set environment variable to a specific value, 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.

3) Resource exhaustion

EUVDB-ID: #VU77953

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-1206

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to a hash collision flaw in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when an attacker makes a new kind of SYN flood attack. A remote attacker can increase the CPU usage of the server that accepts IPV6 connections up to 95%.

Mitigation

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

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.

7) Out-of-bounds read

EUVDB-ID: #VU82659

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-2023-39189

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the nfnl_osf_add_callback() function in Linux kernel Netfilter. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and execute arbitrary code with elevated privileges.

Mitigation

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

EUVDB-ID: #VU79714

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-2023-40283

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 l2cap_sock_release() function in net/bluetooth/l2cap_sock.c. 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.

Risk: Low

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-2023-42754

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 ipv4_send_dest_unreach() function in net/ipv4/route.c. A local user with CAP_NET_ADMIN permissions can perform a denial of service (DoS) attack.

Mitigation

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

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4622

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 unix_stream_sendpage() function in af_unix component. 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.

EUVDB-ID: #VU81664

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4623

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 the Linux kernel net/sched: sch_hfsc (HFSC qdisc traffic control) component. 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.
