Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Information exposure through microarchitectural state after transient execution

EUVDB-ID: #VU79262

Risk: Medium

CVSSv4.0: 2.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-40982

CWE-ID: CWE-1342 - Information Exposure through Microarchitectural State after Transient Execution

Exploit availability: No

Description

The vulnerability allows a malicious guest to escalate privileges on the system.

The vulnerability exists due to the way data is shared between threads whereby the AVX GATHER instructions on Intel processors can forward the content of stale vector registers to dependent instructions. A malicious guest can infer data from different contexts on the same core and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

2) Out-of-bounds write

EUVDB-ID: #VU78943

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-2023-3611

CWE-ID: CWE-787 - Out-of-bounds write

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 qfq_change_agg() function in net/sched/sch_qfq.c within the Linux kernel net/sched: sch_qfq component. A local user trigger an out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Install updates from vendor's repository.
