Security Bulletin

This security bulletin contains information about 21 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU23023

Risk: Medium

CVSSv4.0: 4.9 [CVSS:4.0/AV:A/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-2019-19057

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

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

The vulnerability exists due to memory leak within the "mwifiex_pcie_init_evt_ring()" function in "drivers/net/wireless/marvell/mwifiex/pcie.c" file. A remote attacker on the local network can cause a denial of service condition (memory consumption) by triggering "mwifiex_map_pci_memory()" failures.

Mitigation

Install updates from vendor's repository.
