CVE-2026-31662

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC protocol. An attacker can exploit an integer underflow vulnerability by sending duplicate group acknowledgment messages GRPACKMSG. This causes the bcackers counter to wrap around, leading to persistent network...

CVE-2026-31660

A flaw was found in the Linux kernel's Near Field Communication NFC pn533 driver. This vulnerability arises from an issue in how the driver manages receive buffers. When processing incoming data, the driver may attempt to write to a non-existent buffer if a new one fails to allocate. This can lea...

CVE-2026-31629

A flaw was found in the Linux kernel's Near Field Communication NFC Logical Link Control Protocol LLCP subsystem. Missing return statements after LLCPCLOSED checks in the nfcllcprecvhdlc and nfcllcprecvdisc functions can lead to a use-after-free vulnerability. This occurs because the system...

CVE-2026-31622

A flaw was found in the Linux kernel's NFC Near Field Communication digital subsystem. A malicious peer device can exploit this vulnerability by sending specially crafted NFC-A anti-collision cascade responses. This allows the peer to exceed the intended cascade depth, leading to a heap overflow ...

Deskflow is a keyboard and mouse sharing app. In 1.20.0, 1.26.0.134, and earlier, Deskflow daemon runs as SYSTEM and exposes an IPC named pipe with WorldAccessOption enabled. The daemon processes privileged commands without authentication, allowing any local unprivileged user to execute arbitrary...

CVE-2026-31629

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: add missing return after LLCPCLOSED checks In nfcllcprecvhdlc and nfcllcprecvdisc, when the socket state is LLCPCLOSED, the code correctly calls releasesock and nfcllcpsockput but fails to return. Execution falls throu...

CVE-2026-31622

In the Linux kernel, the following vulnerability has been resolved: NFC: digital: Bounds check NFC-A cascade depth in SDD response handler The NFC-A anti-collision cascade in digitalinrecvsddres appends 3 or 4 bytes to target-nfcid1 on each round, but the number of cascade rounds is controlled...

CVE-2026-31545

In the Linux kernel, the following vulnerability has been resolved: NFC: nxp-nci: allow GPIOs to sleep Allow the firmware and enable GPIOs to sleep. This fixes a WARNON' and allows the driver to operate GPIOs which are connected to I2C GPIO expanders. -- 8 -- kernel: WARNING: CPU: 3 PID: 2636 at...

CVE-2026-31660 nfc: pn533: allocate rx skb before consuming bytes

In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: allocate rx skb before consuming bytes pn532receivebuf reports the number of accepted bytes to the serdev core. The current code consumes bytes into recvskb and may already hand a complete frame to pn533recvframe befo...

CVE-2026-31660

The CVE-2026-31660 entry concerns the Linux kernel NFC pn533 driver. The root cause is that pn532_receive_buf() may hand a complete frame to pn533_recv_frame() before allocating a fresh receive buffer; if alloc_skb() fails, the callback returns 0 while bytes have already been consumed, leaving re...
