Microsoft’s public CVE entry and VEX attestation for CVE-2025-38474 names Azure Linux as a Microsoft-maintained product that includes the upstream code in question and is therefore potentially affected, but that statement is a scoped inventory attestation — not a categorical claim that no other...

Microsoft’s short public notice that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate for the Azure Linux images that Microsoft has inventory‑checked — but it is not a technical guarantee that no other Microsoft product contains the same...

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

Microsoft’s short public answer — 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 technical proof that no other Microsoft product or image could contain the same vulnerable kernel code...

A small but important fix landed in the Linux kernel’s F2FS codebase has been assigned CVE‑2025‑38347 — a change that introduces a sanity check on inode numbers (ino) and extended-attribute node IDs (xnid) to prevent a class of malformed‑image-induced kernel hangs and panics, and Microsoft’s...

Microsoft’s terse MSRC note 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 inventory attestation, not a technical guarantee that no other Microsoft artifact can carry the same vulnerable...

Microsoft’s short public answer — that Azure Linux “includes this open‑source library and is therefore potentially affected” — is correct and useful, but it is product‑scoped, not a universal exclusion of other Microsoft artifacts; absence of attestations for other Microsoft products is not...

Microsoft’s brief MSRC wording that “Azure Linux includes this open‑source library and is therefore potentially affected” is factually correct for the Azure Linux product family, but it is a product‑scoped attestation — not a categorical statement that no other Microsoft product could contain...

A recently assigned CVE, CVE-2025-68324, patches a classic kernel glitch in the Linux IMM parallel-port SCSI driver that allowed a use-after-free to occur when a delayed work item was still pending as the driver instance was torn down — the fix adds a synchronous cancellation to ensure the...

Microsoft’s short, machine‑readable advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is an inventory attestation for a single product family, not proof that no other Microsoft artifact can or does contain the same vulnerable...

Microsoft’s MSRC advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑level attestation, not a universal guarantee that other Microsoft products are free of the same Linux kernel Bluetooth code implicated by...

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 a categorical claim that Azure Linux is the only Microsoft product that could include the vulnerable code. Background /...

A recent upstream Linux kernel fix for CVE‑2025‑37961 addresses an uninitialized-value (KMSAN) finding in the IP Virtual Server (IPVS) codepath — specifically an uninitialized saddr value in do_output_route4 — and Microsoft’s Security Response Center (MSRC) has published an attestation that...

Microsoft’s brief MSRC attestation that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate as a product‑scoped inventory statement — but it is not proof that no other Microsoft product could include the same vulnerable Linux kernel component...

Microsoft confirmed a Windows kernel elevation-of-privilege flaw tracked as CVE-2024-30099 on June 11, 2024 — a time-of-check/time-of-use (TOCTOU) race-condition in kernel code that Microsoft rated as an important local Elevation of Privilege (EoP) and patched in the June 11, 2024 cumulative...

The Linux kernel has received a critical stability fix for a use‑after‑free in its NVMe stack: CVE‑2025‑68265 — described upstream as "nvme: fix admin request_queue lifetime" — which corrects the controller teardown ordering so that the controller's admin request_queue cannot be referenced after...

The Linux kernel has been assigned CVE-2025-68175 for a flaw in the NXP i.MX8 ISI (Image Sensor Interface) driver that can prematurely tear down an active video stream when userland issues a harmless query — a defect fixed upstream by moving streaming preparation and cleanup into the vb2...

The Linux kernel received a small but important patch that closes CVE-2025-68214 — a race in timer_shutdown_sync that could clear a timer’s function pointer while that timer was still active on another CPU, leaving a pending timer with a NULL callback and triggering a WARN_ON inside...

The Linux kernel received a targeted fix for CVE-2025-68193 that changes how the Intel Xe GuC control transport (CT) is torn down: maintainers added a devm-managed release action to ensure the CT is disabled before its backing buffer object (CTB) is freed, closing a deterministic use‑after‑free...

A small but critical defensive check landed in the AMDGPU Atom interpreter this month: a missing allocation check in amdgpu_atom_execute_table_locked could leave the driver with a NULL "WS" workspace pointer while its size field was non-zero, creating a deterministic NULL‑dereference that can...
