CVE-2026-43032

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description In the NFC pn533 component, the pn532 receive buf() function appends incoming bytes to dev->recv skb and only resets the buffer upon recognition of a complete frame by pn532 uart rx is frame(). A continuous stream of bytes lacking a valid PN532 frame header causes the skb to grow until skb put u8() reaches the tail limit.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
