CVE published 26 Oct 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (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 or the CVSS exploit maturity 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.

AI-suggested

A security update is available in kernel version 5.14.0-687.61.1.el9_8 for Red Hat Enterprise Linux 9.8 Extended Update Support. Users should apply this update promptly and reboot the system for the changes to take effect. Red Hat recommends treating all kernel errata as security-relevant and applying updates accordingly.

Description

This security advisory addresses multiple vulnerabilities and bugs in the Linux kernel, including CVE-2024-57974 which involves a race condition between UDP socket address change and rehash. The update also fixes several other kernel issues such as use-after-free errors, integer overflows, and kernel panics. These issues affect the core Linux operating system kernel and are important for system stability and security. The update is available for Red Hat Enterprise Linux 9.8 Extended Update Support and requires a system reboot to take effect.

Impact

The vulnerabilities fixed in this update could lead to race conditions, use-after-free errors, integer overflows, and kernel panics, potentially affecting system stability and security. Exploitation could cause denial of service or other unintended behavior in the kernel. No known exploits in the wild have been reported for CVE-2024-57974. The kernel's fundamental role means these bugs have a higher chance of impacting system security and reliability.

Summary

The Linux kernel packages contain multiple security fixes including CVE-2024-57974, which resolves a race condition between UDP socket address change and rehash operations. Additional fixes address use-after-free vulnerabilities in USB and RAID5 components, integer overflow in encrypted keys, and kernel panics caused by out-of-bounds reads. The advisory covers a broad range of kernel subsystems such as fuse, net/handshake, ipvs, selinux, KVM, usbfs, smb client, vfio/pci, md/raid5-ppl, KEYS encrypted, and netfilter flowtable. These fixes are included in the kernel version 5.14.0-687.61.1.el9_8 and later.
