High severity · No CVSS score from NVD or the CNA

KEV deadline: 25 Mar 2025 US federal agencies must patch by this date; a sensible deadline for everyone else.
EPSS: 0.8% chance of exploitation in 30 days – higher than 56% of CVEsExploit Prediction Scoring System: the likelihood attackers will use this flaw soon.
Patch: Available – fixed in 8.10.0

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 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 8.10.0.

Description

Red Hat has issued a security advisory for kernel-rt packages in Red Hat Enterprise Linux 8, addressing multiple vulnerabilities including zero-initialization of HID report buffers, out-of-bound accesses in USB audio drivers, a potential deadlock in the megaraid_sas driver, and a use-after-free in the pps subsystem. These vulnerabilities affect the Real Time Linux Kernel used for systems requiring high determinism. The update is rated as Important by Red Hat Product Security and requires a system reboot after applying the patch.

Impact

These vulnerabilities could lead to system instability, potential denial of service, or memory corruption due to out-of-bound accesses and use-after-free conditions in kernel components. The advisory rates the overall security impact as Important, indicating a high severity but not critical. There are no known exploits in the wild at the time of the advisory.

Mitigation

Red Hat has released updated kernel-rt packages that address these vulnerabilities. Users should apply the security update as detailed in Red Hat advisory RHSA-2025:2474 and reboot the system to ensure the fixes take effect. No additional mitigation steps are indicated by the vendor.

Summary

The kernel-rt packages for Red Hat Enterprise Linux 8 contain several security vulnerabilities: CVE-2024-50302 involves zero-initializing the HID report buffer to prevent potential issues; CVE-2024-53197 fixes out-of-bound accesses in ALSA USB audio drivers for Extigy and Mbox devices; CVE-2024-57807 addresses a potential deadlock in the megaraid_sas SCSI driver; and CVE-2024-57979 resolves a use-after-free vulnerability in the pps subsystem. These issues have been fixed in updated kernel-rt packages. The advisory references Red Hat's official errata RHSA-2025:2474 and provides links for patch application instructions.

CWE-908Use of Uninitialized Resource (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product uses or accesses a resource that has not been initialized.
Implementation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Implementation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Implementation
Avoid race conditions (CWE-362) during initialization routines.
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
CWE-120Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #11
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output 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…
