Echo: linux: security update to 6.1.180-1

medium Tenable Self-Hosted Container Security Plugin ID 461996

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: USB: chaoskey: Fix slab-use-after-free
 in chaoskey_release() The chaoskey driver has a use-after-free bug in its release routine. If the user
 closes the device file after the USB device has been unplugged, a debugging log statement will try to
 access the usb_interface structure after it has been deallocated: BUG: KASAN: slab-use-after-free in
 dev_driver_string (drivers/base/core.c:2406) Read of size 8 at addr ffff888168e8a0b8 by task
 chaoskey_raw_re/10106 Hardware name: QEMU Ubuntu 24.04 PC v2 (i440FX + PIIX, arch_caps fix, 1996), BIOS

 fput_close_sync (fs/file_table.c:615) __x64_sys_close (fs/open.c:1507 fs/open.c:1492 fs/open.c:1492)
 do_syscall_64 (arch/x86/entry/syscall_64.c:63 arch/x86/entry/syscall_64.c:94)
 entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:121) The driver's last reference to the
 interface structure is dropped in the chaoskey_free() routine, so the code must not use the interface --
 even in a debugging statement -- after that routine returns. (Exception: If we know that another reference
 is held by someone else, such as the device core while the disconnect routine runs, there's no problem.
 Thanks to Johan Hovold for pointing this out.) Since the bad access is part of an unimportant debugging
 statement, we can fix the problem simply by removing the whole statement. (CVE-2026-64455)

Solution

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