CVE-2022-49923 Details
Description
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.
A memory leak vulnerability has been identified in the Linux kernel's NFC subsystem, specifically within the NXP-NCI driver. The issue arises in the 'nxp_nci_send()' function, which calls 'nxp_nci_i2c_write()' to send data over I2C. The vulnerability occurs because the 'nxp_nci_send()' function only frees the socket buffer (skb) when 'nxp_nci_i2c_write()' fails. If 'nxp_nci_i2c_write()' succeeds, the skb is not freed, leading to a memory leak. To address this, 'nxp_nci_send()' should be modified to free the skb even when 'nxp_nci_i2c_write()' is successful.
