Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 462267

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: sctp: diag: reject stale associations
 in dump_one path The SCTP exact sock_diag lookup can hold a transport reference, block on lock_sock(sk),
 and then resume after sctp_association_free() has marked the association dead and freed its bind address
 list. When that happens, inet_assoc_attr_size() and inet_diag_msg_sctpasoc_fill() can still dereference
 association state that is no longer valid for reporting. In particular, inet_diag_msg_sctpasoc_fill() may
 read an empty bind-address list as a real sctp_sockaddr_entry and trigger an out-of-bounds read from
 unrelated association memory. Reject the association after taking the socket lock if it has been reaped or
 detached from the endpoint, and report the lookup as stale. This keeps the exact dump-one path from
 formatting torn association state. (CVE-2026-52917)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
