Detailsinfo

A vulnerability was found in Linux Kernel up to 5.10.153/5.15.77/6.0.7. It has been classified as critical. Affected is the function nxp_nci_send of the component nfc. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. CVE summarizes:

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.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2022-49923 since 05/01/2025. There are known technical details, but no exploit is available.
