CVE-2025-37874

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-37874
In the Linux kernel, the following vulnerability has been resolved: net: ngbe: fix memory leak in ngbe_probe() error path When ngbe_sw_init() is called, memory is allocated for wx->rss_key in wx_init_rss_key(). However, in ngbe_probe() function, the subsequent error paths after ngbe_sw_init() don't free the rss_key. Fix that by freeing it in error path along with wx->mac_table. Also change the label to which execution jumps when ngbe_sw_init() fails, because otherwise, it could lead to a double free for rss_key, when the mac_table allocation fails in wx_sw_init().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: ngbe: corrección de pérdida de memoria en la ruta de error de ngbe_probe() Cuando se llama a ngbe_sw_init(), se asigna memoria para wx->rss_key en wx_init_rss_key(). Sin embargo, en la función ngbe_probe(), las rutas de error posteriores a ngbe_sw_init() no liberan rss_key. Solucione esto liberándolo en la ruta de error junto con wx->mac_table. Cambie también la etiqueta a la que salta la ejecución cuando falla ngbe_sw_init(), porque de lo contrario, podría provocar una doble liberación de rss_key, cuando falla la asignación de mac_table en wx_sw_init().
