  2. Vulnerabilities (CVE)
  3. CVE-2024-27396
In the Linux kernel, the following vulnerability has been resolved: net: gtp: Fix Use-After-Free in gtp_dellink Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal of gtp_dellink, is not part of the RCU read critical section, it is possible that the RCU grace period will pass during the traversal and the key will be free. To prevent this, it should be changed to hlist_for_each_entry_safe.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: gtp: corrige Use-After-Free en gtp_dellink Dado que call_rcu, que se llama en el recorrido hlist_for_each_entry_rcu de gtp_dellink, no forma parte de la sección crítica de lectura de RCU, es posible que el período de gracia de RCU pasará durante el recorrido y la clave quedará libre. Para evitar esto, se debe cambiar a hlist_for_each_entry_safe.
