CVE-2024-38612

  2. Vulnerabilities (CVE)
  3. CVE-2024-38612
In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix invalid unregister error path The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL is not defined. In that case if seg6_hmac_init() fails, the genl_unregister_family() isn't called. This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible use-after-free and null-ptr-deref") replaced unregister_pernet_subsys() with genl_unregister_family() in this error path.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ipv6: sr: corrige la ruta de error de cancelación de registro no válida La ruta de error de seg6_init() es incorrecta en caso de que CONFIG_IPV6_SEG6_LWTUNNEL no esté definido. En ese caso, si seg6_hmac_init() falla, no se llama a genl_unregister_family(). Este problema existe desde que el commit 46738b1317e1 ("ipv6: sr: agregar opción para controlar la compatibilidad con lwtunnel") y el commit 5559cea2d5aa ("ipv6: sr: corregir posible use-after-free y null-ptr-deref") reemplazó unregister_pernet_subsys() con genl_unregister_family() en esta ruta de error.
