PT-2026-128555

In the Linux kernel, the following vulnerability has been resolved: tty: port: fix tty port tty vhangup race Drivers rely on tty port tty vhangup to synchronously hang up their ports before tearing down resources as part of deregistration e.g. on physical disconnect. If tty port tty vhangup races...

In the Linux kernel, the following vulnerability has been resolved: staging: greybus: uart: fix tty use after free User space can hold a tty open indefinitely, and tty drivers must not release the underlying structures until the last user is gone. Switch to using the tty-port reference counter to...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: In tty: goldfish, use ttyportdestroy to destroy the port. In goldfishttyprobe, the port initialized through ttyportinit should be destroyed in error paths. In goldfishttyremove, qtty-port also should be destroyed; otherwise,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: serial: Fixed the race condition where tty-port wasn’t set. The commit bfc467db60b7 “serial: removed redundant ttyportlinkdevice” was reverted because ttyportlinkdevice isn’t redundant. We need to configure tty-port before callin...
