Improper locking in Linux kernel - CVE-2022-50098

Vulnerability identifier: #VU111579

CSH Severity: Low

CVSS v4 BT: 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-2022-50098

CWE-ID: CWE-667

Exploitation vector: Local access

Exploit availability: No public exploit available

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

The vulnerability exists due to improper locking within the qla2xxx_eh_abort(), qla2x00_eh_wait_for_pending_commands(), qla2xxx_eh_device_reset() and qla2xxx_eh_target_reset() functions in drivers/scsi/qla2xxx/qla_os.c. A local user can perform a denial of service (DoS) attack.
