CVE-2026-97916 accel/ivpu: Validate firmware log buffer metadata

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Validate firmware log buffer metadata The tracing log headers parsed by fwlogprintbuffer reside in DMA-shared BOs that the NPU firmware can write to. fwlogfrombo validated log-headersize and log-size, but...

The vulnerability of the fw_log_print_buffer() function in the drivers/accel/ivpu/ivpu_fw_log.c file of the Linux kernel’s acceleration device driver allows a hacker to access protected information or cause a service failure.

The vulnerability of the fwlogprintbuffer function in the drivers/accel/ivpu/ivpufwlog.c file of the Linux kernel’s acceleration device driver module is related to the occurrence of operations outside the buffer’s memory boundaries. Exploiting this vulnerability can allow an attacker to access...
