failed to prevent guests from undoing/replacing such mappings
CVE: CVE-2021-28694
Component: xen
CVSS v3: 5.9/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
Release date: 2021-08-25T00:00:00+00:00

IOMMU page mapping issues on x86 T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Both AMD and Intel allow ACPI tables to specify regions of memory which should be left untranslated, which typically means these addresses should pass the translation phase unaltered. While these are typically device specific ACPI properties, they can also be specified to apply to a range of devices, or even all devices. On all systems with such regions Xen failed to prevent guests from undoing/replacing such mappings (CVE-2021-28694). On AMD systems, where a discontinuous range is specified by firmware, the supposedly-excluded middle range will also be identity-mapped (CVE-2021-28695). Further, on AMD systems, upon de-assigment of a physical device from a guest, the identity mappings would be left in place, allowing a guest continued access to ranges of memory which it shouldn't have access to anymore (CVE-2021-28696).

regulator: rt4801: Fix NULL pointer dereference if priv-&gt;enable_gpios is NULL
CVE: CVE-2021-47233
Component: kernel
CWE: CWE-476
Severity: Moderate
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

A vulnerability was found in the Linux kernel's regulator driver for the RT4801. The issue occurs when the function tries to access a GPIO setting, but it fails because the associated pointer is NULL which lead to crash the system  when the system attempts to use these GPIOs without proper checks.

Statement: None of the products shipped by Red Hat are affected by this vulnerability.

perf/core: Fix unconditional security_locked_down() call
CVE: CVE-2021-46971
Component: kernel
CWE: CWE-413
Severity: Low
CVSS v3: 7.2/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Release date: 2021-01-01T00:00:00+00:00

In the Linux kernel, the following vulnerability has been resolved:

perf/core: Fix unconditional security_locked_down() call

Currently, the lockdown state is queried unconditionally, even though
its result is used only if the PERF_SAMPLE_REGS_INTR bit is set in
attr.sample_type. While that doesn't matter in case of the Lockdown LSM,
it causes trouble with the SELinux's lockdown hook implementation.

SELinux implements the locked_down hook with a check whether the current
task's type has the corresponding "lockdown" class permission
("integrity" or "confidentiality") allowed in the policy. This means
that calling the hook when the access control decision would be ignored
generates a bogus permission check and audit record.

Fix this by checking sample_type first and only calling the hook when
its result would be honored.

Statement: No Red Hat Products are affected by this vulnerability.

Release date: 2021-01-01T00:00:00+00:00

A vulnerability was found in the Linux kernel's ixgbe driver, where a NULL pointer dereference caused under certain conditions when the ixgbe_xdp_setup function is called, leads system panic and instability.

Statement: This vulnerability is classified as moderate severity because it does not expose sensitive data or allow remote exploitation, resulting in NULL pointer dereference which can disrupt system operations and affect stability.

Release date: 2021-07-13T00:00:00+00:00

If Thunderbird was configured to use STARTTLS for an IMAP connection, and an attacker injected IMAP server responses prior to the completion of the STARTTLS handshake, then Thunderbird didn't ignore the injected data. This could have resulted in Thunderbird showing incorrect information, for example the attacker could have tricked Thunderbird to show folders that didn't exist on the IMAP server. This vulnerability affects Thunderbird < 78.12.

Release date: 2021-01-01T00:00:00+00:00

In the Linux kernel, the following vulnerability has been resolved:

KVM: SVM: Make sure GHCB is mapped before updating

Access to the GHCB is mainly in the VMGEXIT path and it is known that the
GHCB will be mapped. But there are two paths where it is possible the GHCB
might not be mapped.

The sev_vcpu_deliver_sipi_vector() routine will update the GHCB to inform
the caller of the AP Reset Hold NAE event that a SIPI has been delivered.
However, if a SIPI is performed without a corresponding AP Reset Hold,
then the GHCB might not be mapped (depending on the previous VMEXIT),
which will result in a NULL pointer dereference.

The svm_complete_emulated_msr() routine will update the GHCB to inform
the caller of a RDMSR/WRMSR operation about any errors. While it is likely
that the GHCB will be mapped in this situation, add a safe guard
in this path to be certain a NULL pointer dereference is not encountered.

Release date: 2021-11-02T00:00:00+00:00

The Mozilla Foundation Security Advisory describes this flaw as:

Microsoft introduced a new feature in Windows 10 known as Cloud Clipboard which, if enabled, will record data copied to the clipboard to the cloud, and make it available on other computers in certain scenarios. Applications that wish to prevent copied data from being recorded in Cloud History must use specific clipboard formats; and Firefox before versions 94 and ESR 91.3 did not implement them. This could have caused sensitive data to be recorded to a user's Microsoft account. This bug only affects Firefox for Windows 10+ with Cloud Clipboard enabled. Other operating systems are unaffected.

Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS without full verification of the SSL/TLS certificate due to the default setting of httpClient. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution.
