CVE-2024-43886 (Moderate severity, published 2024-08-25)
CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-476
Description: In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Add null check in resource_log_pipe_topology_update

[WHY]
When switching from "Extend" to "Second Display Only" we sometimes
call resource_get_otg_master_for_stream on a stream for the eDP,
which is disconnected. This leads to a null pointer dereference.

[HOW]
Added a null check in dc_resource.c/resource_log_pipe_topology_update.
Statement: Following issue marked as moderate with "not affected or will not fix" 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.
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-2024-25580 (Moderate severity, published 2024-02-14)
CVSS score: 6.2 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-121
Description: A vulnerability has been discovered in Qt Base, wherein an attacker can exploit a specially crafted KTX image file to induce a buffer overflow within the application parsing it. This overflow can subsequently result in a denial-of-service condition, rendering the affected application inaccessible or non-responsive.
Statement: The CVE-2024-25580 vulnerability in Qt's KTX image handling module is classified as having a moderate severity rather than being deemed important due to several factors. While the vulnerability does pose a risk of buffer overflow and potential application crashes, its impact is somewhat mitigated by the fact that exploitation requires a specifically crafted KTX image file. This implies that successful exploitation depends on the attacker's ability to provide such a file to the target application. Moreover, the vulnerability does not inherently lead to remote code execution or compromise of sensitive data; it primarily results in a denial-of-service condition through application crashes.
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 base or stability.
CVE-2024-35979 (Low severity, published 2024-05-19)

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

raid1: fix use-after-free for original bio in raid1_write_request()

r1_bio->bios[] is used to record new bios that will be issued to
underlying disks, however, in raid1_write_request(), r1_bio->bios[]
will set to the original bio temporarily. Meanwhile, if blocked rdev
is set, free_r1bio() will be called causing that all r1_bio->bios[]
to be freed:

raid1_write_request()
 r1_bio = alloc_r1bio(mddev, bio); -> r1_bio->bios[] is NULL
 for (i = 0;  i < disks; i++) -> for each rdev in conf
  // first rdev is normal
  r1_bio->bios[0] = bio; -> set to original bio
  // second rdev is blocked
  if (test_bit(Blocked, &rdev->flags))
   break

 if (blocked_rdev)
  free_r1bio()
   put_all_bios()
    bio_put(r1_bio->bios[0]) -> original bio is freed

Test scripts:

CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
Description: A vulnerability was found in the Linux kernel's net driver phy_device.c in the phy_get_internal_delay() function, where a lack of proper checks can cause a potential NULL pointer dereference to occur when the function attempts to access an empty array. The error occurs if the driver calls phy_get_internal_delay() without defining delay_values and rx-internal-delay-ps or tx-internal-delay-ps is set to 0 in the device-tree. This flaw can lead to system instability.
CVE-2024-27417 (Moderate severity, published 2024-05-16)
CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
Description: A flaw was discovered in the Linux kernel's IPv6 implementation, specifically within the inet6_rtm_getaddr() function. The issue arises when user space provides a valid IFA_TARGET_NETNSID value but omits the IFA_ADDRESS and IFA_LOCAL attributes. In such cases, the function returns an -EINVAL error while inadvertently increasing the reference count of the struct net object, leading to a potential memory leak. This flaw has been addressed by ensuring that the reference count is properly managed, preventing unintended resource retention. Users are advised to update their Linux kernel to a version that includes this fix to maintain system stability and prevent resource leaks.

CWE: CWE-416
Description: A failure flaw was found in the Linux kernel’s AMDGPU driver in how a user sends ioctl with an invalid address and size when using the AMD GPU. This flaw allows a local user to crash the system.
Statement: Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-416: Use After Free vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.

Access to the platform is granted only after successful hard token-based multi-factor authentication (MFA) and is governed by least privilege to ensure that only authorized users and roles can execute or modify code. Red Hat also enforces least functionality, enabling only essential features, services, and ports. Hardening guidelines ensure the most restrictive settings required for operations, while baseline configurations enforce safe memory allocation and deallocation practices to reduce the risk of use-after-free vulnerabilities. The environment employs IPS/IDS and antimalware solutions to detect and prevent malicious code and provide real-time visibility into memory usage, lowering the risk of arbitrary code execution. Static code analysis and peer reviews enforce strong input validation and error handling, reducing the likelihood of denial-of-service (DoS) attacks. In the event of successful exploitation, process isolation prevents a compromised process from accessing memory freed by another, containing potential impact. Finally, memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) enhance resilience against memory-related vulnerabilities.

Description: [REJECTED CVE] A vulnerability was identified in the Linux kernel’s powerpc/pseries/iommu subsystem, where dynamically adding a PCI device during Dynamic Logical Partitioning (DLPAR) could trigger a NULL pointer dereference, leading to a kernel oops. This occurred due to the missing initialization of the iommu_device structure in newly allocated pci_controller instances, unlike during system boot where iommu_device_register() is properly invoked. An attacker with the ability to repeatedly add and remove PCI devices could exploit this flaw to trigger system crashes, potentially causing a denial-of-service (DoS) condition

CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
Description: In the Linux kernel, the following vulnerability has been resolved:

cpu: Re-enable CPU mitigations by default for !X86 architectures

Rename x86's to CPU_MITIGATIONS, define it in generic code, and force it
on for all architectures exception x86.  A recent commit to turn
mitigations off by default if SPECULATION_MITIGATIONS=n kinda sorta
missed that "cpu_mitigations" is completely generic, whereas
SPECULATION_MITIGATIONS is x86-specific.

Rename x86's SPECULATIVE_MITIGATIONS instead of keeping both and have it
select CPU_MITIGATIONS, as having two configs for the same thing is
unnecessary and confusing.  This will also allow x86 to use the knob to
manage mitigations that aren't strictly related to speculative
execution.

Use another Kconfig to communicate to common code that CPU_MITIGATIONS
is already defined instead of having x86's menu depend on the common
CPU_MITIGATIONS.  This allows keeping a single point of contact for all
of x86's mitigations, and it's not clear that other architectures *want*
to allow disabling mitigations at compile-time.
Statement: Following issue marked as moderate with "not affected or will not fix" 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.
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.

CWE: CWE-611
Description: A flaw was found in libxml2. In the affected versions of libxml2, the SAX parser can generate events for external entities, even if custom SAX handlers try to override entity content by setting it to "checked." This vulnerability allows classic  XML External Entity (XXE) attacks.
Statement: This vulnerability is marked as critical severity instead of important due to its potential to completely compromise system security. By exploiting the XXE vulnerability, an attacker can achieve arbitrary file disclosure (e.g., reading `/etc/passwd`), which exposes sensitive system information and credentials. 

In worst-case scenarios, the flaw can lead to Remote Code Execution (RCE) in misconfigured environments or cause a Denial of Service (DoS) through resource exhaustion. The issue is especially critical because it stems from a broken protection mechanism (due to the renaming of the "checked" member), silently leaving downstream applications vulnerable without their knowledge.
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.

CWE: CWE-754
Description: In the Linux kernel, the following vulnerability has been resolved:

posix-clock: Fix missing timespec64 check in pc_clock_settime()

As Andrew pointed out, it will make sense that the PTP core
checked timespec64 struct's tv_sec and tv_nsec range before calling
ptp->info->settime64().

As the man manual of clock_settime() said, if tp.tv_sec is negative or
tp.tv_nsec is outside the range [0..999,999,999], it should return EINVAL,
which include dynamic clocks which handles PTP clock, and the condition is
consistent with timespec64_valid(). As Thomas suggested, timespec64_valid()
only check the timespec is valid, but not ensure that the time is
in a valid range, so check it ahead using timespec64_valid_strict()
in pc_clock_settime() and return -EINVAL if not valid.

There are some drivers that use tp->tv_sec and tp->tv_nsec directly to
write registers without validity checks and assume that the higher layer
has checked it, which is dangerous and will benefit from this, such as
hclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),
and some drivers can remove the checks of itself.

CWE: CWE-1333
Description: A flaw was found in DOMPurify. This issue may allow an attacker to use specially-crafted HTML to bypass the depth checking or use Prototype Pollution to weaken the depth check, which can lead to cross site scripting (XSS) attacks.
Statement: The vulnerability in DOMPurify, while significant, is categorized as moderate severity rather than important due to its specific conditions for exploitation. The issue requires not only a sophisticated nesting technique to bypass the depth checks but also the ability to leverage Prototype Pollution to weaken these protections. This makes the attack scenario relatively complex and less likely to be encountered in general use cases. Furthermore, the flaw impacts only certain configurations and usage patterns, thus reducing its immediate risk.
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-2024-27397 (Moderate severity, published 2024-05-07)

Description: A use-after-free flaw was found in the Linux kernel’s netfilter subsystem in how a user triggers the element timeout. This flaw allows a local user to crash or potentially escalate their privileges on the system.
Statement: This vulnerability impact level between Moderate and High, and chosen Moderate.
Mitigation: In order to trigger the issue, it requires the ability to create user/net namespaces.

On non-containerized deployments of Red Hat Enterprise Linux 8, you can disable user namespaces by setting user.max_user_namespaces to 0:

# echo "user.max_user_namespaces=0" > /etc/sysctl.d/userns.conf
# sysctl -p /etc/sysctl.d/userns.conf

On containerized deployments, such as Red Hat OpenShift Container Platform, do not use this mitigation as the functionality is needed to be enabled.

CWE: CWE-476
Description: A flaw was found in the nginx HTTP/3 implementation. This issue may allow an attacker using a specially crafted QUIC session to trigger a NULL pointer dereference error, causing worker processes to crash and lead to a denial of service.
Statement: As this flaw allows a remote attacker to cause a denial of service, it has been rated with an important severity.

The nginx package as shipped in Red Hat Enterprise Linux 8, 9 and RHSCL is not affected by this vulnerability because the support for HTTP/3 is not enabled and the vulnerable code was introduced in a later version of nginx.
