Echo: linux: security update to 6.1.135-1

medium Tenable Self-Hosted Container Security Plugin ID 462794

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: jfs: Prevent copying of nlink with
value 0 from disk inode syzbot report a deadlock in diFree. [1] When calling "ioctl$LOOP_SET_STATUS64",
the offset value passed in is 4, which does not match the mounted loop device, causing the mapping of the
mounted loop device to be invalidated. When creating the directory and creating the inode of iag in
diReadSpecial(), read the page of fixed disk inode (AIT) in raw mode in read_metapage(), the metapage data
it returns is corrupted, which causes the nlink value of 0 to be assigned to the iag inode when executing
copy_from_dinode(), which ultimately causes a deadlock when entering diFree(). To avoid this, first check
the nlink value of dinode before setting iag inode. [1] WARNING: possible recursive locking detected
