Echo: linux: security update to 6.1.180-1

medium Tenable Self-Hosted Container Security Plugin ID 463203

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btmtksdio: fix infinite
 loop in btmtksdio_txrx_work() Every once in a while we see a hung btmtksdio_flush() task: INFO: task
 kworker/u17:0:189 blocked for more than 122 seconds. __cancel_work_timer+0x3f4/0x460
 cancel_work_sync+0x1c/0x2c btmtksdio_flush+0x2c/0x40 hci_dev_open_sync+0x10c4/0x2190 [..] It all boils
 down to incorrect time_is_before_jiffies() usage in btmtksdio_txrx_work(). The btmtksdio_txrx_work() loop
 is expected to be terminated if running for longer than 5*HZ. However the timeout check is twisted:
 time_is_before_jiffies(old_jiffies + 5*HZ) evaluates to true when old_jiffies + 5*HZ is in the past i.e.
 when a timeout has occurred. Using OR with time_is_before_jiffies(txrx_timeout) means that: - before the
 5-second timeout: the condition is `int_status || false`, so it loops as long as there are pending
 interrupts. - after the 5-second timeout: the condition becomes `int_status || true`, which is always
 true. When the loop becomes infinite btmtksdio_txrx_work() loop never terminates and never releases the
 SDIO host. Fix loop termination condition to actually enforce a 5*HZ timeout. (CVE-2026-64409)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
