medium Tenable Self-Hosted Container Security Plugin ID 459130

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: nfc: nci: free skb on nci_transceive
 early error paths nci_transceive() takes ownership of the skb passed by the caller, but the -EPROTO,
 -EINVAL, and -EBUSY error paths return without freeing it. Due to issues clearing NCI_DATA_EXCHANGE fixed
 by subsequent changes the nci/nci_dev selftest hits the error path occasionally in NIPA, and kmemleak
 detects leaks: unreferenced object 0xff11000015ce6a40 (size 640): comm "nci_dev", pid 3954, jiffies
