Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-05-07 15:31

Details

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.

Severity

5.5 (Medium)
