kernel security update
An update for kernel is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2.
he Linux Kernel, the operating system core itself.
Security Fix(es):
A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.(CVE-2021-3640)
An update for kernel is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2.
openEuler Security has rated this update as having a security impact of low. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
