USN-8095-4

linux-aws-6.8 vulnerabilities

Published Mar 23, 2026 · corrected/updated Oct 14, 2026 · evidence confidence medium

Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM). An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege escalation, or possibly escape a container. (LP: #2143853) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - MIPS architecture; - Nios II architecture; - PA-RISC architecture; - RISC-V architecture; - S390 architecture; - Sun Sparc architecture; - User-Mode Linux (UML); - x86 architecture; - Xtensa architecture; - Block layer subsystem; - Cryptographic API; - Compute Acceleration Framework; - ACPI drivers; - ATM drivers; - Drivers core; - Block device driver; - Network block device driver; - Bluetooth drivers; - Bus devices; - Hardware random number generator core; - Character device driver; - Data acquisition framework and drivers; - CPU frequency scaling framework; - Hardware crypto device drivers; - Device frequency scaling framework; - DMA engine subsystem; - ARM SCMI message protocol; - EFI core; - Intel Stratix 10 firmware drivers; - GPU drivers; - HID subsystem; - CoreSight HW tracing drivers; - IIO subsystem; - InfiniBand drivers; - Input Device core drivers; - Input Device (Miscellaneous) drivers; - Input Device (Tablet) drivers; - IOMMU subsystem; - ISDN/mISDN subsystem; - Mailbox framework; - Multiple devices driver; - Media drivers; - Fastrpc Driver; - MOST (Media Oriented Systems Transport) drivers; - MTD block device drivers; - Ethernet bonding driver; - Network drivers; - Mellanox network drivers; - STMicroelectronics network drivers; - Texas Instruments network drivers; - Ethernet team driver; - NVME drivers; - PCI subsystem; - PCCARD (PCMCIA/CardBus) bus subsystem; - Performance monitor drive

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

USN-8095-4 is a unknown public vulnerability record for this product. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether this product is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: linux-aws-6.8 (0 → 6.8.0-1050.53~22.04.1). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.

Security analyst

Signals on file: no CVSS/EPSS yet. It is not currently listed in the CISA Known Exploited catalog. Sources contributing to this record: osv. Public exploit references, when present, are outbound links only and are not proof of active exploitation. This is a catalog interpretation of stored metadata.

Exploitation and remediation

Exploitation evidence
Not listed as known exploited in CISA KEV. Not in the CISA KEV catalog.
Patch and remediation
No required-action text is stored yet. Use the vendor or CERT links in Sources for patch availability.
Safe detection guidance
Compare installed versions with the affected ranges below and verify the advisory from the original publisher. This site stores metadata and outbound links only; it does not ship exploit code or proof-of-concept payloads.
