| Description: | Summary:
The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2021-0489 advisory.
Vulnerability Insight:
This kernel update is based on upstream 5.10.75 and fixes at least the
following security issues:
A memory leak in the ccp_run_aes_gcm_cmd() function in drivers/crypto/
ccp/ccp-ops.c in the Linux kernel allows malicious users to cause a
denial of service (memory consumption) (CVE-2021-3744).
A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd()
function that allows an malicious user to cause a denial of service
(CVE-2021-3764).
A race condition accessing file object in the Linux kernel OverlayFS
subsystem was found in the way users do rename in specific way with
OverlayFS. A local user could use this flaw to crash the system
(CVE-2021-20321).
prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel
through 5.14.9 allows unprivileged users to trigger an eBPF multiplication
integer overflow with a resultant out-of-bounds write (CVE-2021-41864).
For other upstream fixes, see the referenced changelogs.
