1) Use-after-free

EUVDB-ID: #VU81923

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-2023-1192

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.

EUVDB-ID: #VU77953

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

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.

EUVDB-ID: #VU75769

Risk: Medium

CVSSv4.0: 4.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

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.

6) Out-of-bounds read

EUVDB-ID: #VU81920

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-39193

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

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the sctp_mt_check() function in Netfilter subsystem in Linux kernel. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and read contents of memory on the system.

Mitigation

12) Use-after-free

EUVDB-ID: #VU80177

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-4563

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 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

15) Use-after-free

EUVDB-ID: #VU81693

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-2023-4921

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 the qfq_dequeue() function within the the Linux kernel's net/sched: sch_qfq component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation
