Last modified
CVE-2022-49923 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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(). EPSS estimates a 0.15% chance of exploitation in the next 30 days.
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.
