Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free.\n\nWe recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c."},{"lang":"es","value":"Se puede explotar una vulnerabilidad de use-after-free en el componente Linux kernel's af_unix para lograr una escalada de privilegios local.
