CVE-2026-80797

A flaw was found in the Near Field Communication NFC PN533 driver in the Linux kernel. When a PN533 device is removed while data fragments are still queued, the driver's cleanup process fails to properly release these fragments, resulting in a memory leak. This can lead to system instability or...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: A temporary reference to the request skb must be held during the sendframe call. The pn533sendasync function publishes the command and then calls dev-phyops-sendframe. Once dev-cmd is set, an incoming frame can be...

PT-2026-94570

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the NFC PN533 driver where the request skb socket buffer can be freed while the transport is still using it. This occurs because pn533 send async publishes the...
