Echo: linux: security update to 6.1.162-1

medium Tenable Cloud Security Plugin ID 457128

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: ocfs2: fix kernel BUG in
 ocfs2_find_victim_chain syzbot reported a kernel BUG in ocfs2_find_victim_chain() because the
 `cl_next_free_rec` field of the allocation chain list (next free slot in the chain list) is 0, triggring
 the BUG_ON(!cl->cl_next_free_rec) condition in ocfs2_find_victim_chain() and panicking the kernel. To fix
 this, an if condition is introduced in ocfs2_claim_suballoc_bits(), just before calling
 ocfs2_find_victim_chain(), the code block in it being executed when either of the following conditions is
 true: 1. `cl_next_free_rec` is equal to 0, indicating that there are no free chains in the allocation
 chain list 2. `cl_next_free_rec` is greater than `cl_count` (the total number of chains in the allocation
 chain list) Either of them being true is indicative of the fact that there are no chains left for usage.
 This is addressed using ocfs2_error(), which prints the error log for debugging purposes, rather than
 panicking the kernel. (CVE-2025-68771)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
