USN-8492-1: Linux kernel vulnerabilities

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; - PowerPC architecture; - x86 architecture; - Block layer subsystem; -...

SUSE CVE-2026-53057

In the Linux kernel, the following vulnerability has been resolved: iommu/riscv: Add IOTINVAL after updating DDT/PDT entries Add riscviommuiodiriotinval to perform required TLB and context cache invalidations after updating DDT or PDT entries, as mandated by the RISC-V IOMMU specification Section...

The vulnerabilities of the functions si_domain_init() and init_dmars() in the drivers/iommu/intel/iommu.c file of the Linux operating system’s IOMMU kernel driver allow a attacker to cause a service failure.

The vulnerability of the functions sidomaininit and initdmars in the drivers/iommu/intel/iommu.c file of the Linux operating system’s IOMMU driver module is related to a memory leak. Exploiting this vulnerability could allow an attacker to cause a service failure...

Linux Distros Unpatched Vulnerability : CVE-2026-53312

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - iommu/riscv: Remove overflows on the invalidation path Since RISC-V supports a sign extended page table it should support a gather-end of ULONGMAX, but if this...

CVE-2026-53283

A flaw was found in the Linux kernel's AMD IOMMU Input/Output Memory Management Unit driver. A local attacker or a specially configured PCI device could trigger an out-of-bounds read in the rlookupamdiommu function. This vulnerability occurs when a PCI device's Bus Device Function BDF is not...

CVE-2026-53280

A flaw was found in the Linux kernel's Input-Output Memory Management Unit IOMMU component. This vulnerability occurs when a default IOMMU domain fails to allocate during the initial probe, leading to a NULL pointer dereference. This can cause a system crash, resulting in a Denial of Service DoS...

SUSE CVE-2026-53281

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Avoid NULL pointer dereference or refcount corruption Commit 60f030f7418d "iommu/vt-d: Avoid use of NULL after WARNONONCE" fixed a NULL pointer dereference in an unlikely situation partly. If devpasid is not found in...
