kernel patch

The Linux kernel patch addressing CVE-2023-53209 fixes a simple but consequential logic error in the mac80211 hardware‑simulation driver (mac80211_hwsim): the code could call mac80211_hwsim_select_tx_link and dereference a station pointer (sta) without verifying it was non‑NULL, creating a...

A small but important kernel patch fixing CVE-2025-40223 closes a race that could produce a use‑after‑free (UAF) in the MOST USB driver’s disconnect path, converting a KASAN‑reported crash into a deterministic and safe device release sequence and removing redundant device reference adjustments...

The Linux kernel has been updated to fix CVE-2025-40240, a small but important defensive bug in the SCTP receive path that could trigger a kernel NULL-pointer dereference when a chunk’s data buffer is missing; the upstream patch reorders checks and uses the chunk header instead of dereferencing...

A small code hygiene fix landed in upstream stable trees this week to close an information‑disclosure hole in the Linux input subsystem: CVE‑2025‑40035 addresses an uninitialized‑stack leak in the uinput compat path by explicitly zeroing an instance of uinput_ff_upload_compat before it is copied...

Linux kernel developers have patched CVE-2025-40052 — a buffer-management bug in the SMB client that can trigger kernel BUGs when cryptographic operations run over non‑linear (vmalloc) memory — after reports that parallel encrypted I/O on SMB mounts can hit a scatterlist validation failure and...

The Linux kernel has been assigned CVE‑2025‑40077 for a narrowly scoped arithmetic fix in the F2FS filesystem: a single-line defensive cast (casting folio->index to loff_t before shifting) prevents a left‑shift arithmetic overflow that could otherwise produce incorrect offsets during...

The Linux kernel entry for CVE-2022-49552 closes a subtle but practical correctness bug in the BPF JIT pipeline: a mismatch between the kernel’s jit blinding pass and how BPF subprogram pointers are handled could cause the kernel to attempt execution at an invalid address and crash, producing a...

A small, surgical patch landed upstream this week to close CVE-2025-40010 — a null-pointer dereference in the Linux kernel’s AFS code — and while the fix is minimal it illustrates an important reality for kernel maintainers and administrators: tiny defensive-programming omissions in privileged...

Valve’s quiet effort to keep a 13‑year‑old Radeon GPU working on modern Linux is a vivid reminder that software maintenance—and who chooses to do it—matters as much as hardware age when it comes to device longevity. While Microsoft prepares to stop regular updates for Windows 10 on October 14...

Microsoft’s Security Response Center has published an advisory for CVE‑2025‑53140, a use‑after‑free vulnerability in the Windows Kernel Transaction Manager (KTM) that Microsoft says can be exploited by an authorized local attacker to elevate privileges on an affected system. Background /...

The Microsoft Surface Pro 11, unveiled in June 2024, marked a significant shift in the Surface lineup by integrating Qualcomm's Snapdragon X series processors, specifically the Snapdragon X Elite and X Plus. This transition to ARM architecture brought notable enhancements in performance and...

A wave of crucial fixes and updates has swept across the Windows ecosystem as Microsoft addresses two major setbacks encountered in the deployment of the Windows 11 24H2 update. These recent technical challenges—one affecting enterprise-grade rollout via Windows Server Update Services (WSUS) and...

Microsoft’s forthcoming shift to a paid subscription model for Windows Server hotpatching represents not just a pricing change, but a significant evolution in how enterprise customers will manage server security and uptime. Administrators responsible for keeping mission-critical services running...

Amid significant developments in operating system management, Microsoft has announced a major shift for one of the most lauded features previewed in Windows Server 2025: hotpatching. This transition, confirmed by multiple reputable sources including Microsoft documentation and industry analysis...
