Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SPI: sun6i – Fixing the race condition between DMA RX transfer completion and RX FIFO drain. Previously, the transfer-completion interrupt would immediately drain the RX FIFO to read any remaining data in the FIFO into the RX...

UBUNTU-CVE-2026-68466

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: lpc32xxslc: fail DMA transfer on completion timeout lpc32xxxmitdma waits for the DMA completion callback but ignores waitforcompletiontimeout. A timed out DMA transfer is therefore unmapped and reported as successfu...

CVE-2026-68329

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Wait for completion instead of returning early in iommucompletionwait needsync is a per-IOMMU flag shared by all domains and devices behind that IOMMU. It is set whenever a command is queued with sync == true and clear...

CVE-2026-68329

CVE-2026-68329 affects the Linux kernel’s iommu/amd path. A race in iommu_completion_wait() can cause it to return before all previously queued commands complete, enabling a use-after-free window where stale page-table translations may be used. The issue stems from need_sync being read locklessly...

PT-2026-69729

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A logical race condition exists in the AMD IOMMU implementation within the iommu completion wait function. The issue occurs because the need sync flag is read without a lock and can retu...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: moving waitonsem out of the spinlock With iommu.strict=1, the existing completion wait mechanism can cause soft lockups in stressed environments. This occurs because waitonsem performs busy waits under a spinlock when...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Thermal: Core – Fix the error path in thermal zone device registration If the thermalzonedeviceregisterwithtrips function fails after registering a thermal zone device, it needs to wait for the completion of tz-removal like when...

CVE-2026-43469

Summary: CVE-2026-43469 affects the Linux kernel xprtrdma component. The root cause is that rpcrdma_post_recvs() may exit early or fail to create a work request without decrementing ep->re_receiving. This miscount can cause rpcrdma_xprt_drain() to hang, leaving the completion blocked and poten...

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: move waitonsem out of spinlock With iommu.strict=1, the existing completion wait path can cause soft lockups under stressed environment, as waitonsem busy-waits under the spinlock with interrupts disabled. Move the...

CVE-2026-43253

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: move waitonsem out of spinlock With iommu.strict=1, the existing completion wait path can cause soft lockups under stressed environment, as waitonsem busy-waits under the spinlock with interrupts disabled. Move the...

CVE-2026-43253

CVE-2026-43253 relates to the Linux kernel IOMMU AMD component. When iommu.strict=1, the wait_on_sem() busy-wait runs inside a spinlock with interrupts disabled, risking soft lockups under load. The fix moves the completion wait out of the spinlock in iommu_completion_wait(), since wait_on_sem() ...
