Echo: linux: security update to 6.7.7-1

medium Tenable Cloud Security Plugin ID 460297

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: md: Don't register sync_thread for
 reshape directly Currently, if reshape is interrupted, then reassemble the array will register sync_thread
 directly from pers->run(), in this case 'MD_RECOVERY_RUNNING' is set directly, however, there is no
 guarantee that md_do_sync() will be executed, hence stop_sync_thread() will hang because
 'MD_RECOVERY_RUNNING' can't be cleared. Last patch make sure that md_do_sync() will set MD_RECOVERY_DONE,
 however, following hang can still be triggered by dm-raid test shell/lvconvert-raid-reshape.sh
 occasionally: [root@fedora ~]# cat /proc/1982/stack [<0>] stop_sync_thread+0x1ab/0x270 [md_mod] [<0>]

 do_syscall_64+0xc6/0x230 [<0>] entry_SYSCALL_64_after_hwframe+0x6c/0x74 Meanwhile mddev->recovery is:
 MD_RECOVERY_RUNNING | MD_RECOVERY_INTR | MD_RECOVERY_RESHAPE | MD_RECOVERY_FROZEN Fix this problem by
 remove the code to register sync_thread directly from raid10 and raid5. And let md_check_recovery() to
 register sync_thread. (CVE-2024-26756)
