CVE-2026-43291
EUVD-2026-2856108.05.2026, 14:16
In the Linux kernel, the following vulnerability has been resolved:
net: nfc: nci: Fix parameter validation for packet data
Since commit 9c328f54741b ("net: nfc: nci: Add parameter validation for
packet data") communication with nci nfc chips is not working any more.
The mentioned commit tries to fix access of uninitialized data, but
failed to understand that in some cases the data packet is of variable
length and can therefore not be compared to the maximum packet length
given by the sizeof(struct).EnginsightAffected Products (NVD)
