In the Linux kernel, the following vulnerability has been resolved: vmxnet3: fix BUGON in vmxnet3gethdrlen for Geneve packets vmxnet3gethdrlen assumes gdesc-rcd.v4/v6/tcp always describe the outer header, but for a Geneve-encapsulated packet the device can set them based on the inner header...

CVE-2026-68184

The CVE-2026-68184 issue affects the Linux kernel CD-ROM code, specifically mmc_ioctl_cdrom_volume for CDROMVOLCTRL. A 32-byte stack buffer is used to read the audio control mode page (buflen 24, then extended if a block descriptor is present). The function later builds a MODE SELECT payload by m...

CVE-2026-68178

CVE-2026-68178 concerns the Linux kernel NSM (Network Shared Memory) misc device. The root cause is that misc_open() installs file_operations with fops_get() which pins file_operations::owner, but NSM’s misc device left nsm_dev_fops.owner unset, allowing an open /dev/nsm descriptor to survive an ...

CVE-2026-68129

CVE-2026-68129 concerns the Linux kernel gve driver. Under extreme memory pressure, Rx buffer allocations can fail during the receive (Rx) buffer refill loop, causing the number of buffers posted to hardware to drop below a critical threshold and leading to a permanent queue stall. Consequences d...
