  3. CVE-2022-49923
In the Linux kernel, the following vulnerability has been resolved: nfc: nxp-nci: Fix potential memory leak in nxp_nci_send() nxp_nci_send() will call nxp_nci_i2c_write(), and only free skb when nxp_nci_i2c_write() failed. However, even if the nxp_nci_i2c_write() run succeeds, the skb will not be freed in nxp_nci_i2c_write(). As the result, the skb will memleak. nxp_nci_send() should also free the skb when nxp_nci_i2c_write() succeeds.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfc: nxp-nci: Se corrige una posible fuga de memoria en nxp_nci_send(). nxp_nci_send() llamará a nxp_nci_i2c_write() y solo liberará skb cuando nxp_nci_i2c_write() falle. Sin embargo, incluso si la ejecución de nxp_nci_i2c_write() tiene éxito, skb no se liberará en nxp_nci_i2c_write(). Como resultado, skb sufrirá una fuga de memoria. nxp_nci_send() también debería liberar skb cuando nxp_nci_i2c_write() tenga éxito.
