Echo: linux: security update to 6.1.180-1

high Tenable Self-Hosted Container Security Plugin ID 463201

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: netfilter: ebtables: terminate table
 name before find_table_lock() update_counters() and compat_update_counters() forward a user-supplied
 32-byte table name to find_table_lock() without NUL-terminating it. On a lookup miss, find_inlist_lock()
 calls try_then_request_module(..., "%s%s", "ebtable_", name), and vsnprintf() reads past the name field
 and the stack object until it hits a zero byte. BUG: KASAN: stack-out-of-bounds in string
 (lib/vsprintf.c:648 lib/vsprintf.c:730) Read of size 1 at addr ffff8880119dfb20 by task exploit/147 Call
 Trace: ... string (lib/vsprintf.c:648 lib/vsprintf.c:730) vsnprintf (lib/vsprintf.c:2945) __request_module
 (kernel/module/kmod.c:150) do_update_counters.isra.0 (net/bridge/netfilter/ebtables.c:371
 net/bridge/netfilter/ebtables.c:380) update_counters (net/bridge/netfilter/ebtables.c:1440) do_ebt_set_ctl
 (net/bridge/netfilter/ebtables.c:2573) nf_setsockopt (net/netfilter/nf_sockopt.c:101) ip_setsockopt
 (net/ipv4/ip_sockglue.c:1424) raw_setsockopt (net/ipv4/raw.c:847) __sys_setsockopt (net/socket.c:2393) ...
 compat_do_replace() shares the same unterminated name via compat_copy_ebt_replace_from_user(); terminate
 it there too so all find_table_lock() callers behave alike. The other callers already terminate the name
 after the copy. (CVE-2026-64411)

Solution

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