CVE-2025-23156

In the Linux kernel, the following vulnerability has been resolved:

media: venus: hfi_parser: refactor hfi packet parsing logic

words_count denotes the number of words in total payload, while data points to payload of various property within it. When words_count reaches last word, data can access memory beyond the total payload. This can lead to OOB access. With this patch, the utility api for handling individual properties now returns the size of data consumed. Accordingly remaining bytes are calculated before parsing the payload, thereby eliminates the OOB access possibilities.

This flaw does not affect Red Hat Enterprise Linux or other Red Hat products because the Qualcomm Venus media driver is not enabled in supported kernel configurations. The issue exists in the Host Firmware Interface packet parser for specific Qualcomm video accelerator hardware, which is excluded from enterprise builds. As the vulnerable code is not present, Red Hat systems are not exposed to this security risk.
