Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU63662
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-2021-3573
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows local user to escalate their privileges on the system.
The vulnerability exists due to a use-after-free in hci_sock_bound_ioctl() function of the Linux kernel HCI subsystem triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user can use this flaw to crash the system or escalate privileges on the system.
MitigationUpdate the affected package the Linux Kernel (Live Patch 22 for SLE 15 SP1) to the latest version.
