The Linux kernel received a small but important patch closing a race that could lead to a kernel use‑after‑free in the SCSI target iSCSI code: CVE‑2026‑23216 fixes a timing window in iscsit_dec_conn_usage_count() where the code called complete() while still holding a connection spinlock...

A subtle but consequential race in the Linux kernel’s memory-control-group (memcg) ID management has been fixed: CVE-2024-43892 describes an insufficiently synchronized idr_remove() path on mem_cgroup_idr that could let multiple memcgs acquire the same ID and, in concrete fleets, has been linked...

A race condition in the Linux kernel's Marvell mvpp2 network driver can corrupt the parser TCAM/SRAM state and silently deny network availability by dropping all incoming unicast traffic — a bug tracked as CVE-2025-22060 that was fixed in upstream kernel trees by serializing access to the...

A recently recorded Linux-kernel vulnerability affects the FORE200E ATM driver: a small but meaningful synchronization bug in fore200e_open that can corrupt the driver’s bandwidth accounting when error paths run concurrently with normal control operations. The upstream fix is straightforward —...

A race condition in the Linux kernel's macintosh input driver has been patched after security tooling discovered a double list insertion bug that can corrupt kernel lists and trigger instability when multiple processes write the same sysctl concurrently. Background The vulnerability, tracked as...

A subtle race in the Linux kernel’s Tegra GPU host1x syncpoint allocation and release code was fixed upstream by switching to an atomic kref-based release helper, closing CVE-2025-68732 and eliminating a timing window where a syncpoint could be re-allocated while it was still being cleaned up...

A newly recorded Linux kernel vulnerability, tracked as CVE-2025-68261, fixes a subtle race in ext4 by adding i_data_sem protection to ext4_destroy_inline_data_nolock, closing a window where inline-data teardown and block-mapping can collide and trigger a kernel BUG or panic. Background /...

A livelock in the Linux FUSE stack that can freeze I/O workers has been fixed upstream: CVE‑2025‑40220 patches a pathological interaction between AIO-driven client behavior and fuseblk server threads by turning synchronous file‑put operations into asynchronous ones to break a self‑referential...

A recent Linux kernel fix closes CVE-2025-40027, a race-condition bug in the net/9p client that could cause a double removal of a request from its tracking list — a logic race that KASAN and syzkaller surfaced as a general-protection fault and list corruption during heavy fuzzing of 9p client...

Microsoft’s decision to let organizations stream single Windows applications from the cloud — instead of entire Cloud PC sessions — marks a pragmatic pivot in how enterprises will adopt Windows 365 for day-to-day workforces and frontline roles. The new Windows 365 Cloud Apps feature, now in...

CVE-2025-55226 is a locally exploitable race‑condition vulnerability in the Windows Graphics Kernel that allows an authenticated (local) attacker to achieve code execution in kernel context by inducing concurrent access to a shared graphics subsystem resource without proper synchronization. This...

As the software landscape continually evolves, Microsoft’s renewed push for secure coding has taken a pivotal turn with the formal encouragement of Rust as a first-class language for Windows driver development. This strategic endorsement, once a future-looking promise, is rapidly becoming...

A newly uncovered and actively exploited vulnerability in Microsoft’s Remote Desktop Gateway (RD Gateway) has sent ripples through the cybersecurity community, marking a significant risk for organizations dependent on secure remote access solutions. This flaw, cataloged as CVE-2025-21297, was...

Node.js has established itself as a bedrock technology for backend web development, thanks to its asynchronous programming model, robust JavaScript ecosystem, and continuous improvements since its inception in 2009. With giants like Netflix, PayPal, and LinkedIn building at scale on Node.js, its...

I am developing an online booking platform that enables teachers to arrange online conversations with students. Teachers can indicate the dates and times they are available for virtual meetings. Students are able to find available teachers by entering the date, time, and duration for interviews...

We are excited to announce that the Rust/WinRT project finally has a permanent and public home on GitHub: microsoft/winrt-rs Rust/WinRT follows in the tradition established by C++/WinRT of building language projections for the Windows Runtime using standard languages and compilers, providing a...

Ever wish there were a way to condense the entire CppCon 2015 into less than an hour? Well, realistically speaking, there may not be a way to really do that, but we hope this month's episode comes close! CppCon 2015 was packed to the brim with all sorts of great content, great people, and great...
