Add the missing kfree() for the BO array before freeing the hang state struct. The Linux kernel CVE team has assigned CVE-2026-43105 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/vc4/vc4_gem.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/a812008fe3a0aebb778d277b35717f64e23d0302 https://git.kernel.org/stable/c/0d3c014a84396a147705f523a8fd6fc873e76502 https://git.kernel.org/stable/c/421cea4f71f7cf65abaae878562ee4aa2b684628 https://git.kernel.org/stable/c/b8138567c4a80fd76a647849ebd4284996cf4b17 https://git.kernel.org/stable/c/f4dfd6847b3e5d24e336bca6057485116d17aea4
