[USN-4879-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 49
CVEs 2
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

It was discovered that the Marvell WiFi-Ex device driver in the Linux
kernel did not properly validate ad-hoc SSIDs. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2020-36158)

Loris Reiff discovered that the BPF implementation in the Linux kernel did
not properly validate attributes in the getsockopt BPF hook. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2021-20194)
