Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: serial: imx: fix tx statemachine deadlock When using the serial port as a RS485 port, the tx statemachine is used to control the RTS pin to drive the RS485 transceiver’s TXEN pin. When the TTY port is closed mid-transmission e.g....

CVE-2026-72124

A flaw was found in the Linux kernel's Controller Area Network CAN ISO-TP transport protocol module. A race condition in the transmit TX state machine allows for unsynchronized state transitions. This can lead to a situation where a frame or timer callback operates on an outdated state, resulting...

CVE-2026-72124

In the Linux kernel, the following vulnerability has been resolved: can: isotp: serialize TX state transitions under so-rxlock The TX state machine so-tx.state is driven from three contexts: sendmsg claiming and progressing a transfer, the RX path consuming Flow Control/echo frames, and two...

CVE-2026-72124

Summary: CVE-2026-72124 affects the Linux kernel CAN isotp TX state machine. The bug arose from mixing a lock-free cmpxchg() claim in sendmsg() with hrtimer_cancel() under so->rx_lock, creating windows where a frame or timer callback could operate on a migrated TX state and corrupt an unrelate...
