CVE-2026-74551 hwmon: (nzxt-smart2) DMA-align output buffer

In the Linux kernel, the following vulnerability has been resolved: hwmon: nzxt-smart2 DMA-align output buffer Sashiko reports: When sendoutputreport calls hidhwoutputreport, the underlying USB HID core calls usbinterruptmsg which maps this buffer directly for DMA. When the DMA mapping flushes or...

CVE-2026-74551

CVE-2026-74551 affects the Linux kernel hwmon path for nzxt-smart2. The issue arises when send_output_report() triggers USB HID DMA mapping via hid_hw_output_report(), which maps the output buffer for DMA using usb_interrupt_msg(). On non-coherent CPUs (e.g., ARM/MIPS), flushing/invalidating the ...

CVE-2026-74548

CVE-2026-74548 affects the Linux kernel’s forcedeth driver, where nv_remove() frees per-CPU txrx_stats before unregister_netdev(), allowing a use-after-free for txrx_stats accessed by ndo_get_stats64, the NAPI/xmit data path, and nv_close()/drain until unregistration completes. The fix delays fre...

CVE-2026-74545

In the Linux kernel, the following vulnerability has been resolved: rtase: fix double free of multi-frag skb on DMA map failure In rtasestartxmit, when the head buffer DMA mapping fails after rtasexmitfrags has mapped all fragments, the error path clears the fragment descriptors with...

CVE-2026-74545

CVE-2026-74545 is a Linux kernel issue where rtase_start_xmit() can double-free an skb on DMA map failure after fragments are mapped. The fix changes control flow to return immediately after clearing fragments when the skb owns frags; the no-frag path still frees the head skb once. Public advisor...

CVE-2026-74543

CVE-2026-74543 concerns the Linux kernel UDP tunnel NIC offload code. The issue: when device registration fails, the code may leak a struct udp_tunnel_nic due to an early return if utn->work_pending is set, because no subsequent NETDEV_UNREGISTER rebroadcast occurs. The fix, as described in co...
