Actively exploited

High severity · No CVSS score from NVD or the CNA

KEV deadline: 26 Feb 2025 US federal agencies must patch by this date; a sensible deadline for everyone else.
EPSS: 3.3% chance of exploitation in 30 days – higher than 88% of CVEsExploit Prediction Scoring System: the likelihood attackers will use this flaw soon.
Patch: Available – fixed in 9.3

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CISA KEV (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Red Hat kernel-rt to 9.3.

Affected software

Product	Affected	Fixed in
Red Hat Product Security Red Hat	Affected >=9.2 <9.3 Red Hat Red Hat Enterprise Linux Red Hat Enterprise Linux Real Time EUS (v.9.2) Red Hat Enterprise Linux Real Time for NFV EUS (v.9.2) src	Fixed in 9.3

Description

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: media: uvcvideo: Skip parsing frames of type UVC_VS_UNDEFINED in uvc_parse_format (CVE-2024-53104) * kernel: mm: fix NULL pointer dereference in alloc_pages_bulk_noprof (CVE-2024-53113) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

The vulnerabilities could cause system instability or crashes due to improper handling of undefined video frames and NULL pointer dereferences in kernel memory allocation. This may lead to denial of service conditions on affected systems running the vulnerable kernel-rt versions. No known exploits in the wild have been reported.

Mitigation

Red Hat has released an official security update for kernel-rt packages in Red Hat Enterprise Linux 9.2 EUS that addresses these vulnerabilities. Users should apply the update as described in the Red Hat advisory (https://access.redhat.com/articles/11258) and reboot their systems to ensure the fixes take effect.

Summary

The kernel-rt packages for Red Hat Enterprise Linux 9.2 EUS contain two security vulnerabilities. CVE-2024-53104 is a flaw in the uvcvideo media driver where frames of type UVC_VS_UNDEFINED were parsed improperly, potentially causing unexpected behavior. CVE-2024-53113 is a NULL pointer dereference in the alloc_pages_bulk_noprof function within the kernel memory management code, which could lead to crashes. Red Hat has released updated kernel-rt packages that fix these issues. The update must be applied and the system rebooted to take effect.

CWE-787Out-of-bounds Write (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #5
The product writes data past the end, or before the beginning, of the intended buffer.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Operation · Build and Compilation · Environment Hardening
Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index…

The product dereferences a pointer that it expects to be valid but is NULL.
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished.
Requirements
Select a programming language that is not susceptible to these issues.
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
