EUVD-2026-86649

In the Linux kernel, the following vulnerability has been resolved: virtioconsole: do not free control-out buffers on remove sendcontrolmsg publishes &portdev-cpkt as the control-out virtqueue cookie. removevqs walks every virtqueue and passes leftover cookies to freebuf, which treats them as...

CVE-2026-97995

The Linux kernel contains a vulnerability in the virtio_console driver where the remove_vqs() function incorrectly passes leftover cookies to free_buf(). If a control message remains on c_ovq when a device is unbound, free_buf() treats these cookies as struct port_buffer and reads past the ports_...

CVE-2026-97994 vhost/vdpa: reject VRING_NUM larger than device max

In the Linux kernel, the following vulnerability has been resolved: vhost/vdpa: reject VRINGNUM larger than device max vhostvringsetnum accepts any non-zero power-of-two queue size that fits in 16 bits. vhost-vdpa then passes that value to setvqnum without comparing it with getvqnummax. A process...

CVE-2026-97994

The Linux kernel contains a vulnerability in the vhost-vdpa component where vhost_vring_set_num() accepts a queue size that exceeds the device's maximum capacity without proper validation against get_vq_num_max(). A process with access to /dev/vhost-vdpa-* can exploit this to configure a queue la...

CVE-2026-97991

The Linux kernel contains a vulnerability in vdpa_sim_blk where the vdpasim_blk_check_range() function logs an invalid start sector but fails to halt validation. This allows an unsigned capacity subtraction to underflow, leading to an out-of-range buffer offset reaching the data path. The invalid...

CVE-2026-97976

The Linux kernel contains a vulnerability in the btintel_pcie driver. The function btintel_pcie_submit_rx_work() fails to verify if packet_len read from rfh_hdr exceeds the RX buffer size, potentially leading to an out-of-bounds read in skb_put_data(). Remediation involves validating that packet_...

CVE-2026-97936

The Linux kernel contains a memory corruption vulnerability in the tracing subsystem. The event_hist_trigger() function performs an unbounded memcpy when handling the histogram stacktrace modifier, using a count directly from the event data. This allows for an out-of-bounds write that can overwri...

CVE-2026-97936 tracing: Fix memory corruption from the histogram stacktrace modifier

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix memory corruption from the histogram stacktrace modifier parsefield sets HISTFIELDFLSTACKTRACE from the ".stacktrace" modifier before it looks the field name up, and nothing afterwards checks that the name resolved t...
