Description OSIDB Bzimport 2025-05-01 15:01:39 UTC 
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.
