CVE-2021-47565 (Moderate severity, published 2024-05-23)
CVSS score: 4.7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-399
Description: In the Linux kernel, the following vulnerability has been resolved:

scsi: mpt3sas: Fix kernel panic during drive powercycle test

While looping over shost's sdev list it is possible that one
of the drives is getting removed and its sas_target object is
freed but its sdev object remains intact.

Consequently, a kernel panic can occur while the driver is trying to access
the sas_address field of sas_target object without also checking the
sas_target object for NULL.
Statement: Following issue marked as moderate with "not affected" for Red Hat Enterprise Linux, as it is not vulnerable to this CVE. This is because the CVE does not impact the versions or configurations of the Linux kernel used in Red Hat's distributions. Additionally, some RHEL versions may be marked as "will not fix" due to the minimal impact of the issue, and no fix will be provided.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

CVE-2021-3509 (Moderate severity, published 2021-05-12)

CWE: CWE-79
Description: A flaw was found in the Red Hat Ceph Storage Dashboard. In response to CVE-2020-27839, the JWT token was moved  from localStorage to an httpOnly cookie. However, token cookies are used in the body  of the HTTP response for the documentation, which again makes it available to XSS. The greatest threat to the system is for confidentiality, integrity, and availability.
Statement: Red Hat OpenStack Platform deployments use the ceph package directly from the Ceph channel; the RHOSP package will not be updated at this time.
Red Hat OpenShift Container Storage (RHOCS) 4 shipped ceph package for the usage of RHOCS 4.2 only which has reached End of Life. The shipped version of ceph package is neither used nor supported with the release of RHOCS 4.3.

Red Hat Ceph Storage (RHCS) 4 ships a version of ceph which has not been patched for CVE-2020-27839, and therefore, although not vulnerable to this specific flaw, would be vulnerable if CVE-2020-27839 were to be patched without recognition of the flaw.

Red Hat Enterprise Linux 8 is not affected by this flaw as it does not include the ceph dashboard component.

Description: A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was found in the way users call some interrupts with high frequency from one of the guests.
A local user could use this flaw to starve the resources resulting in a denial of service.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation baser or stability. The possible solution is to disable Bluetooth completely: https://access.redhat.com/solutions/2682931

This issue occurs due to a soft lockup, where the CPU gets stuck for extended periods, causing the system to hang and become unresponsive.
Statement: This vulnerability is rated as a moderate severity because it does not compromise system security or expose data.
Mitigation: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.

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

comedi: dt9812: fix DMA buffers on stack

USB transfer buffers are typically mapped for DMA and must not be
allocated on the stack or transfers will fail.

Allocate proper transfer buffers in the various command helpers and
return an error on short transfers instead of acting on random stack
data.

Note that this also fixes a stack info leak on systems where DMA is not
used as 32 bytes are always sent to the device regardless of how short
the command is.

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

tipc: skb_linearize the head skb when reassembling msgs

It's not a good idea to append the frag skb to a skb's frag_list if
the frag_list already has skbs from elsewhere, such as this skb was
created by pskb_copy() where the frag_list was cloned (all the skbs
in it were skb_get'ed) and shared by multiple skbs.

However, the new appended frag skb should have been only seen by the
current skb. Otherwise, it will cause use after free crashes as this
appended frag skb are seen by multiple skbs but it only got skb_get
called once.

The same thing happens with a skb updated by pskb_may_pull() with a
skb_cloned skb. Li Shuang has reported quite a few crashes caused
by this when doing testing over macvlan devices:

  ...

This patch is to fix it by linearizing the head skb if it has frag_list
set in tipc_buf_append(). Note that we choose to do this before calling
skb_unshare(), as __skb_linearize() will avoid skb_copy(). Also, we can
not just drop the frag_list either as the early time.

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

dm rq: don't queue request to blk-mq during DM suspend

DM uses blk-mq's quiesce/unquiesce to stop/start device mapper queue.

But blk-mq's unquiesce may come from outside events, such as elevator
switch, updating nr_requests or others, and request may come during
suspend, so simply ask for blk-mq to requeue it.

Fixes one kernel panic issue when running updating nr_requests and
dm-mpath suspend/resume stress test.
Statement: This issue is fixed in RHEL-8.6 and above (including 8.10):

initialised.

A floating point exception (FPE) due to an integer divide by zero was found in Exiv2 versions v0.27.4 and earlier. The FPE is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5.
