Description OSIDB Bzimport 2025-02-27 03:02:30 UTC 
In the Linux kernel, the following vulnerability has been resolved:

NFC: nci: Add bounds checking in nci_hci_create_pipe()

The "pipe" variable is a u8 which comes from the network.  If it's more
than 127, then it results in memory corruption in the caller,
nci_hci_connect_gate().
