[USN-5217-1] Linux kernel (OEM) vulnerabilities

Severity High
Affected Packages 13
CVEs 2
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

It was discovered that the NFS server implementation in the Linux kernel
contained an out-of-bounds write vulnerability. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2021-4090)

It was discovered that the eBPF implementation in the Linux kernel did
not properly validate the memory size of certain ring buffer operation
arguments. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2021-4204)
