Hi !
It's this week's CVE report.
This week reported one new CVE.
* New CVEs
CVE-2021-20317: lib/timerqueue: Rely on rbtree semantics for next timer
This bug has been fixed in 5.4-rc1 so that before 5.4 kernels are
affected. For 4.19, patch can be applied without any modification. For
4.4, it needs to modify patch to apply it.
According to the description in
cve.mitre.org(https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-20317),
it describes "This flaw allows a local attacker with special user
privileges to cause a denial of service" so I think this vulnerability
severity may be low.
CVSS v3 score is not provided.
