Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Details

In the Linux kernel, the following vulnerability has been resolved:

nfc: nfcmrvl: Fix potential memory leak in nfcmrvl_i2c_nci_send()

nfcmrvl_i2c_nci_send() will be called by nfcmrvl_nci_send(), and skb should be freed in nfcmrvl_i2c_nci_send(). However, nfcmrvl_nci_send() will only free skb when i2c_master_send() return >=0, which means skb will memleak when i2c_master_send() failed. Free skb no matter whether i2c_master_send() succeeds.
