Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: iommu/amd: Serialize sequence allocation under concurrent TLB invalidations. With concurrent TLB invalidations, the completion wait time might randomly time out. This occurs because the cmdsemval field was incremented outside ...

CVE-2026-43220

A flaw was found in the Linux kernel, specifically within the iommu/amd component responsible for managing memory access. This vulnerability arises from an issue in how commands are processed during concurrent memory invalidations, causing them to be queued out of sequence. This can lead to syste...

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...

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: serialize sequence allocation under concurrent TLB invalidations With concurrent TLB invalidations, completion wait randomly gets timed out because cmdsemval was incremented outside the IOMMU spinlock, allowing...

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() ...

CVE-2026-43220

The CVE-2026-43220 entry concerns the Linux kernel iommu/amd component. The issue arises under concurrent TLB invalidations when CMD_COMPL_WAIT sequencing can be broken because cmd_sem_val was incremented outside the IOMMU spinlock, causing out-of-sequence command queuing and a disrupted completi...
