Exploitation

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 10.2.0

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 2026-10-25.

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 redhat/kernel to 10.2.0.

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: media: uvcvideo: Skip parsing frames of type UVC_VS_UNDEFINED in uvc_parse_format (CVE-2024-53104) * kernel: vsock: Keep the binding until socket destruction (CVE-2025-21756) 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 affect the Linux kernel core components, potentially impacting system stability and security related to media frame parsing and socket binding. Red Hat rates the security impact as important, indicating a significant but not critical risk. There are no known exploits in the wild at this time.

Mitigation

Red Hat has released an official kernel update that addresses these vulnerabilities. Users should apply the update as detailed in the Red Hat advisory and reboot their systems to ensure the fixes take effect. No additional mitigation steps are required beyond applying the official patch.

Summary

This advisory addresses two kernel vulnerabilities in Red Hat Enterprise Linux 10. CVE-2024-53104 fixes an issue in the uvcvideo driver where frames of type UVC_VS_UNDEFINED were parsed, which could lead to unexpected behavior. CVE-2025-21756 fixes a vsock subsystem issue where the socket binding was not kept until socket destruction, potentially causing resource management problems. Red Hat has released patched kernel packages to remediate these vulnerabilities. The update requires a system reboot 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…

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
