2) Deadlock

EUVDB-ID: #VU81900

Risk: Medium

CVSSv3.1: 4.3 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-34324

CWE-ID: CWE-833 - Deadlock

Exploit availability: No

Description

The vulnerability allows a malicious guest to perform a denial of service (DoS) attack.

The vulnerability exists due to improper event handling in Linux kernel. A malicious guest can disable paravirtualized device to cause a deadlock in a backend domain (other than dom0).

Mitigation

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

3) 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.

CVE-ID: CVE-2023-45862

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the ENE UB6250 reader driver in drivers/usb/storage/ene_ub6250.c. A local user can trigger a boundary error and perform a denial of service (DoS) attack.

Mitigation

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