CVE-2026-13351 net: Maliciously fragmented IPv6 packets can prevent receiving/processing future incoming packets
Zephyr's IPv6 network stack can be prevented from receiving or processing future incoming packets by sending a small number of maliciously fragmented IPv6 packets. When such a packet is handled by the fragment-header processing path, the associated RX network packet buffer allocated from a memory...

CVE-2026-10642
The Zephyr PL011 UART driver drivers/serial/uartpl011.c contains an unbounded software loop in pl011irqtxenable that repeatedly invokes the interrupt-driven application callback while the TX interrupt mask bit PL011IMSCTXIM is set, to work around the controller's level-transition TX-interrupt...
CVE-2026-10642 Unbounded TX busy-loop DoS in Zephyr PL011 UART driver under CTS hardware flow control
The Zephyr PL011 UART driver drivers/serial/uartpl011.c contains an unbounded software loop in pl011irqtxenable that repeatedly invokes the interrupt-driven application callback while the TX interrupt mask bit PL011IMSCTXIM is set, to work around the controller's level-transition TX-interrupt...
CVE-2026-10642
The CVE-2026-10642 issue affects the Zephyr PL011 UART driver (drivers/serial/uart_pl011.c) where pl011_irq_tx_enable() can spin in an unbounded loop when CTS hardware flow control is enabled and CTS is de-asserted by the peer. This causes the TX interrupt to remain masked and the controller to s...

Name of the Vulnerable Software and Affected Versions Zephyr versions 4.1.0 through 4.4.0 Description The PL011 UART driver in drivers/serial/uart pl011.c contains an unbounded software loop within the pl011 irq tx enable function. This loop repeatedly invokes the interrupt-driven application...
Linux Distros Unpatched Vulnerability : CVE-2026-10658
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - btisorecv in subsys/bluetooth/host/iso.c pulled the ISO SDU header 4 bytes or, when the timestamp flag is set, the timestamped SDU header 8 bytes from the inbou...
Linux Distros Unpatched Vulnerability : CVE-2026-10645

CVE-2026-10645
The Zephyr ext2 filesystem driver subsys/fs/ext2 trusted the on-disk directory entry fields dereclen and denamelen when walking a directory block. ext2fetchdirentry guarded only with denamelen EXT2MAXFILENAME, but denamelen is a uint8t and EXT2MAXFILENAME is 255, so the check is always false; the...

CVE-2026-10658
CVE-2026-10658 affects Zephyr’s Bluetooth Host ISO RX path, specifically bt_iso_recv() in subsys/bluetooth/host/iso.c. The vulnerability arises from missing minimum length checks for SDU headers when processing PB=START/SINGLE, allowing a malformed HCI ISO payload to bypass the inner header lengt...
