2) Memory leak

EUVDB-ID: #VU23021

Risk: Low

CVSSv4.0: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-19054

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

Exploit availability: No

Description

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

The vulnerability exists due to memory leak within the "cx23888_ir_probe()" function in "drivers/media/pci/cx23885/cx23888-ir.c" file. A local attacker can cause a denial of service condition (memory consumption) by triggering "kfifo_alloc()" failures.

Mitigation

Update the affected package linux to the latest version.

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-2019-19073

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 "htc_config_pipe_credits()", "htc_setup_complete()" and "htc_connect_service()" functions in "drivers/net/wireless/ath/ath9k/htc_hst.c" file. A remote attacker on the local network can cause a denial of service condition (memory consumption) by triggering "wait_for_completion_timeout()" failures.

Mitigation

Update the affected package linux to the latest version.

6) Out-of-bounds read

EUVDB-ID: #VU35550

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-9445

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.
