CVE-2021-3679 CVE-2021-3732 CVE-2021-3739 CVE-2021-3743 CVE-2021-3753 CVE-2021-37576 CVE-2021-38160 CVE-2021-38166 CVE-2021-38199 CVE-2021-40490 CVE-2021-41073 Debian Bug : 993948 993978
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
CVE-2020-3702
A flaw was found in the driver for Atheros IEEE 802.11n family of
chipsets (ath9k) allowing information disclosure.
CVE-2020-16119
Hadar Manor reported a use-after-free in the DCCP protocol
implementation in the Linux kernel. A local attacker can take
advantage of this flaw to cause a denial of service or potentially
to execute arbitrary code.
CVE-2021-3653
Maxim Levitsky discovered a vulnerability in the KVM hypervisor
implementation for AMD processors in the Linux kernel: Missing
validation of the `int_ctl` VMCB field could allow a malicious L1
guest to enable AVIC support (Advanced Virtual Interrupt Controller)
for the L2 guest. The L2 guest can take advantage of this flaw to
write to a limited but still relatively large subset of the host
physical memory.
CVE-2021-3656
Maxim Levitsky and Paolo Bonzini discovered a flaw in the KVM
hypervisor implementation for AMD processors in the Linux kernel.
Missing validation of the the `virt_ext` VMCB field could allow a
malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and VLS
(Virtual VMLOAD/VMSAVE) for the L2 guest. Under these circumstances,
the L2 guest is able to run VMLOAD/VMSAVE unintercepted and thus
read/write portions of the host's physical memory.
CVE-2021-3679
A flaw in the Linux kernel tracing module functionality could allow
a privileged local user (with CAP_SYS_ADMIN capability) to cause a
denial of service (resource starvation).
