CVE-2025-23157

Linux Linux, linux kernel, debian linux

In the Linux kernel, the following vulnerability has been resolved: media: venus: hfi_parser: add check to avoid out of bound access There is a possibility that init_codecs is invoked multiple times during manipulated payload from video firmware. In such case, if codecs_count can get incremented to value more than MAX_CODEC_NUM, there can be OOB access. Reset the count so that it always starts from beginning.

Full remediation guide
  1. 1
    Identify

    Confirm that Linux Linux, linux kernel, debian linux and an affected version are present.

  2. 2
    Prioritize

    Combine exploitation signals with asset exposure and business criticality.

  3. 3
    Remediate

    Follow the vendor advisory or supported update path and preserve rollback options.

  4. 4
    Verify

    Recheck the version, service health, access paths, and relevant logs.
