kernel patching

The Linux kernel received a targeted robustness fix for a device‑mapper ioctl bug tracked as CVE‑2024‑23851: a missing check in copy_params (drivers/md/dm-ioctl.c) could let an ioctl request lead the kernel to try to allocate more than INT_MAX bytes and crash, producing a local denial‑of‑service...

A critical robustness bug in the Linux kernel’s AMDGPU driver—tracked as CVE-2024-42228—allows a local actor to provoke a kernel-level denial-of-service by using an uninitialized value when the driver calls amdgpu_vce_cs_reloc, and upstream fixes have been merged into stable kernel trees and...

The Linux kernel received a targeted fix for a subtle but disruptive bug in its object‑aggregation helper: CVE‑2024‑43846 — “lib: objagg: Fix general protection fault”, a defect that can trigger a general protection fault (GPF) and turn routine operations into a local denial‑of‑service condition...

Microsoft’s advisory around CVE‑2025‑37988 makes an important distinction: the Azure Linux distribution (formerly CBL‑Mariner) is the only Microsoft product that the company has publicly attested contains the vulnerable upstream kernel code — but that admission is a statement about completed...

A small, defensive change in the Linux kernel’s in‑kernel SMB server, ksmbd, has been tracked as CVE‑2025‑37956 and fixed upstream — but Microsoft’s public wording that “Azure Linux includes this open‑source library and is therefore potentially affected” is a product‑scoped attestation, not...

Microsoft’s brief advisory language — that “Azure Linux includes this open‑source library and is therefore potentially affected” — is accurate for the product it names, but it is not an exclusive statement that no other Microsoft product could include the same vulnerable code; in short: Azure...
