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.

Affected configurations

• linux linux kernel (>= 4.4 < 4.9.333) • linux linux kernel (>= 4.10 < 4.14.299) • linux linux kernel (>= 4.15 < 4.19.265) • linux linux kernel (>= 4.20 < 5.4.224) • linux linux kernel (>= 5.5 < 5.10.154) • linux linux kernel (>= 5.11 < 5.15.78) • linux linux kernel (>= 5.16 < 6.0.8) • linux linux kernel 6.1
