Red Hat Security Advisory: kernel security update
This advisory addresses multiple moderate severity vulnerabilities in the Linux kernel packages used by Red Hat Enterprise Linux 10. The issues include a double free vulnerability in the exFAT filesystem (CVE-2025-38206), a potential double free in the DRM scheduler (CVE-2025-40096), a fix in the SMC module for socket destination handling (CVE-2025-40168), and a use-after-free in the mlxsw multicast route stats update (CVE-2025-68800). These vulnerabilities can lead to denial of service or memory corruption. Red Hat has released security updates that fix these issues, and a system reboot is required to apply the updates. The advisory covers multiple architectures and product variants of Red Hat Enterprise Linux 10.

Technical Summary
The Red Hat security advisory RHSA-2026:3275 addresses four kernel vulnerabilities in Red Hat Enterprise Linux 10. CVE-2025-38206 is a double free vulnerability in the exFAT filesystem that can cause denial of service. CVE-2025-40096 fixes a potential double free in drm_sched_job_add_resv_dependencies within the DRM scheduler. CVE-2025-40168 corrects socket destination handling in the smc_clc_prfx_match function by using __sk_dst_get() and dst_dev_rcu(). CVE-2025-68800 resolves a use-after-free issue in the mlxsw spectrum_mr module when updating multicast route statistics. These fixes are included in updated kernel packages requiring a reboot. The advisory does not provide CVSS scores but rates the overall impact as moderate.
Potential Impact
The vulnerabilities can lead to denial of service conditions or memory corruption due to double free or use-after-free bugs in kernel components. Exploitation could cause system instability or crashes. No known exploits in the wild have been reported. The impact is limited to affected Red Hat Enterprise Linux 10 kernel packages across multiple architectures.
Mitigation Recommendations
Red Hat has released updated kernel packages that address these vulnerabilities. Users should apply the security update RHSA-2026:3275 promptly and reboot affected systems to ensure the fixes take effect. Refer to https://access.redhat.com/articles/11258 for update instructions. No additional mitigations are specified or required beyond applying the official patches and rebooting.
