Security Fix(es):
|
||
|
||
A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2021-3759)
|
||
|
||
A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.(CVE-2021-3753)</Note>
|
||
<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">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 medium. 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.</Note>
