      "value": "A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation.\n\nThe unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. 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.\n\n"

La funci\u00f3n  unix_stream_sendpage() intenta a\u00f1adir datos al \u00faltimo skb en la cola peer's recv sin bloquear la cola. Por lo tanto, existe una carrera donde unix_stream_sendpage() podr\u00eda acceder a un skb sin bloqueo que est\u00e1 siendo liberado mediante la recolecci\u00f3n de basura, resultando en use-after-free.
