Microsoft’s brief product attestation that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate for Azure Linux, but it is not a guarantee that no other Microsoft product can include the vulnerable Linux kernel code — any Microsoft artifact that ships...

Microsoft’s concise MSRC wording that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate for the product it names — but it is a product‑scoped attestation, not a guarantee that no other Microsoft product ever shipped the same vulnerable upstream...

The Linux kernel fix tracked as CVE-2025-38125 corrects a simple but dangerous logic error in the STMMAC Ethernet driver: if the driver’s recorded ptp_rate is zero, that bogus value can be propagated into the EST configuration and cause a division‑by‑zero. Microsoft’s public advisory names Azure...

Microsoft’s public advisory names Azure Linux as the Microsoft product that “includes this open‑source library and is therefore potentially affected,” but that statement is an attestation of scope completed so far — it does not prove that no other Microsoft product can or does include the same...

CVE-2025-38234 is a kernel scheduling bug — a race in sched/rt’s push_rt_task — that has been fixed upstream, and Microsoft’s public advisory names Azure Linux as a Microsoft product that “includes this open‑source library and is therefore potentially affected.” That statement is factual and...

Microsoft’s brief public attestation that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑scoped inventory statement, not a guarantee that no other Microsoft product can or does include the vulnerable netfilter code. Azure...

Microsoft’s public advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate for the Azure Linux product family — but it is not a universal guarantee that no other Microsoft product ships the same vulnerable kernel code; the attestation is...

Microsoft’s brief advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑scoped attestation, not an assertion that no other Microsoft product can or does include the same vulnerable kernel code. Background / Overview...

Microsoft’s phrasing that “Azure Linux includes this open‑source library and is therefore potentially affected” is a product‑scoped inventory attestation — not a blanket statement that no other Microsoft product can or does include the same vulnerable code. Background / Overview CVE‑2025‑22109...

A subtle ordering bug in the RISC‑V KVM teardown sequence has been assigned CVE‑2025‑23135 and patched upstream: during module removal the KVM cleanup path could call architecture‑specific cleanup routines in the wrong order, leaving per‑CPU IRQ state inconsistent and preventing the KVM module...

Microsoft’s short advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑scoped attestation, not a categorical statement that no other Microsoft product could include the same vulnerable component. Background /...

Short answer (TL;DR) No — Azure Linux is the only Microsoft product Microsoft has publicly attested (via its MSRC/VEX/CSAF work) to include the upstream btrfs code for CVE‑2025‑22115 so far, but that statement is a scoped inventory attestation, not a proof that no other Microsoft‑distributed...

Microsoft’s concise MSRC wording that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑scoped attestation, not a categorical declaration that no other Microsoft product can or does include the same vulnerable Linux code...

Short answer up front No — Azure Linux is not the only Microsoft product that Microsoft has identified as including the affected ravb code. Microsoft’s CSAF/VEX entry for CVE‑2025‑21801 lists Azure Linux (Azure Linux 3.0) and CBL Mariner kernel builds as known/confirmed components that include...

Microsoft’s brief MSRC advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate for the Azure Linux product family, but it is a product‑scoped attestation — not a categorical claim that no other Microsoft product can include the same...

A small defensive change in the Linux kernel’s DRM subsystem — a missing NULL check in the xe_devcoredump path — was assigned CVE-2024-42081 and patched in mid‑2024; while the fix is trivial in code, the operational impact is real: a NULL assignment in kernel space can yield an immediate kernel...

A null-pointer bug in the Linux kernel’s virtio-pci driver — tracked as CVE-2024-42134 — can be triggered when the driver attempts to use an uninitialized pointer (vp_dev->is_avq) while tearing down virtqueues, allowing an attacker with local privileges to crash a guest and produce a...

The Linux kernel vulnerability tracked as CVE-2024-42151 fixes a subtle but dangerous mismatch between how the eBPF verifier reasons about a test-case function parameter and how the test itself actually invokes that function — a situation that can let the verifier elide a NULL check and allow a...

Microsoft’s MSRC advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is an authoritative, product‑scoped attestation — but it is not a categorical guarantee that no other Microsoft product contains the same vulnerable AMDGPU code; Azure Linux is...

The Linux kernel patch credited to CVE‑2024‑42066 fixes a subtle but important arithmetic bug in the DRM XE driver: the code now explicitly casts tbo->page_alignment to a 64‑bit unsigned type (u64) before performing a bit shift used to compute min_page_size, removing a possible integer overflow...
