Photon OS 4.0: Linux PHSA-2021-4.0-0095

high Nessus Plugin ID 153035

Synopsis

The remote PhotonOS host is missing multiple security updates.

Description

An update of the linux package has been released.

 - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

 - In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. NOTE: exploitation might be impractical without the CAP_SYS_ADMIN capability. (CVE-2021-38166)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected Linux packages.
