CVE-2022-49922 Information

Description

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.
