Severity ?
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: NFC: nci: Bounds check struct nfc_target arrays While running under CONFIG_FORTIFY_SOURCE=y, syzkaller reported: memcpy: detected field-spanning write (size 129) of single field "target->sensf_res" at net/nfc/nci/ntf.c:260 (size 18) This appears to be a legitimate lack of bounds checking in nci_add_new_protocol(). Add the missing checks.
