CVE-2026-53203
Last modified
CVE-2026-53203 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
