In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Add buffer overflow check in MS get_info_ioctl Add validation that the info size returned from the metric stream info query is not exceeded when checked against the allocated buffer size. If the firmware returns a size larger than the buffer, reject the operation with -EOVERFLOW instead of proceeding with an incorrect buffer copy.

An update of the linux package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - accel/ivpu: Add buffer overflow check in MS get_info_ioctl Add validation that the info size returned from     the metric stream info query is not exceeded when checked against the allocated buffer size. If the     firmware returns a size larger than the buffer, reject the operation with -EOVERFLOW instead of proceeding     with an incorrect buffer copy. (CVE-2026-53203)

Note that Nessus relies on the presence of the package as reported by the vendor.
