Routine

HIGH 7.8WATCHLIST

CVE-2026-64599 is a high-severity flaw (CVSS 7.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In the Linux kernel, the following vulnerability has been resolved: crypto: amlogic - avoid double cleanup in meson_crypto_probe() When meson_allocate_chanlist() fails after a partial allocation, it already unwinds the allocated chanlist state through its local error path. meson_crypto_probe() then jump to error_flow and calls meson_free_chanlist() again, causing the same per-flow resources to be torn down twice. In the reproduced failure path,
