CVE-ID: CVE-2022-3566

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

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

The vulnerability exists due to a race condition within the tcp_getsockopt() and tcp_setsockopt() functions in net/ipv4/tcp.c, do_ipv6_setsockopt() function in net/ipv6/ipv6_sockglue.c, and tcp_v6_connect() function in net/ipv6/tcp_ipv6.c in Linux kernel. A local user can exploit the race and escalate privileges on the system.

Mitigation

14) Out-of-bounds write

EUVDB-ID: #VU76098

Risk: Low

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-31436

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 within the qfq_change_class() function in net/sched/sch_qfq.c when handling the MTU value provided to the QFQ Scheduler. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

Mitigation

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

15) Use-after-free

EUVDB-ID: #VU76221

Risk: Low

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-32269

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 in net/netrom/af_netrom.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability requires that the system has netrom routing configured or the attacker must have the CAP_NET_ADMIN capability.

Mitigation

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