RHSA-2025:10675
Vulnerability from csaf_redhat - Published: 2025-07-09 00:29 - Updated: 2026-10-14 17:25Summary
Red Hat Security Advisory: kernel-rt security update
Severity
Important
Notes
Topic: An update for kernel-rt is now available for Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: 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: use-after-free in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c (CVE-2023-1652)
* kernel: ext4: ignore xattrs past end (CVE-2025-37738)
* kernel: udf: Fix a slab-out-of-bounds write bug in udf_find_entry() (CVE-2022-49846)
* kernel: net: atlantic: fix aq_vec index out of range error (CVE-2022-50066)
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.

A flaw was found in the Linux kernel's Universal Disk Format (UDF) file system. An out-of-bounds memory write occurs due to an incorrect buffer size calculation when processing long filenames. A local user capable of mounting file systems can trigger this issue by mounting a crafted UDF image and accessing or creating files with specially constructed long names. This flaw leads to kernel memory corruption, potentially allowing privilege escalation or causing a Denial of Service (DoS) via a system crash.

Threats
Impact
Moderate
A vulnerability was found in the Linux kernel's Aquantia Atlantic driver, where a lack of proper bounds checking during loop indexing can lead to an out-of-bounds access. This can lead to undefined system behavior and a denial of service.

Affected products
Fixed
34 products, the same list as for
CVE-2022-49846
Threats
Impact
Moderate
A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem.

Threats
Impact
Moderate
A use-after-free vulnerability has been discovered in the Linux kernel, specifically within the ext4_xattr_inode_dec_ref_all function (related to the ext4 filesystem's extended attributes). An attacker could exploit this flaw by providing a specially crafted payload, leading to a denial of service condition that compromises system availability.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
