What it actually does
Incorrect list head deletion in smc_lgr_cleanup_early instead of the intended link group entry leaves the real structure on the list; subsequent memset of the link group structure corrupts kernel list pointers and triggers list_del validation failures.
Why it matters to the business
Unexpected kernel panics during SMC link teardown can cause sudden system reboots or hangs on servers handling shared-memory network traffic, leading to service disruption and unplanned downtime.
How an attack unfolds
An attacker triggers repeated SMC link establishment and teardown sequences that invoke the faulty cleanup path; the resulting list corruption panics the kernel before the link group is properly removed, achieving denial of service.
How to fix it
Apply the upstream fix that corrects the list_del argument in smc_lgr_cleanup_early; rebuild and deploy the patched kernel image; reboot affected systems after installation.
How to confirm the fix worked
Confirm the corrected list_del call is present in the smc_lgr_cleanup_early function; run kernel regression tests that exercise SMC link down paths and verify absence of list corruption panics.
Typical attack path
- Establish SMC connections to force link group allocation
- Induce link-down events that schedule smc_link_down_work
- Cause smc_lgr_cleanup_early to execute the erroneous list_del
- Trigger subsequent memset that corrupts list pointers
- Observe kernel BUG at lib/list_debug.c and system crash
How to detect it
Search kernel logs and dmesg for 'list_del corruption' and 'invalid opcode' entries originating from __list_del_entry_valid during smc_link_down_work or smc_lgr_terminate_sched; inspect crash dumps for SMC workqueue activity.
- list_del corruption. prev->next should be
- kernel BUG at lib/list_debug.c:53
- smc_link_down_work
- smc_lgr_cleanup_early
What your security team should do
- Prioritize kernel updates on all systems exposing SMC sockets
- Monitor for list_del corruption panics in kernel logs
- Test patched kernels in staging environments before broad rollout
The record
In the Linux kernel, the following vulnerability has been resolved: net/smc: fix wrong list_del in smc_lgr_cleanup_early smc_lgr_cleanup_early() meant to delete the link group from the link group list, but it deleted the list head by mistake. This may cause memory corruption since we didn't remove the real link group from the list and later memseted the link group structure. We got a list corruption panic when testing: [ 231.277259] list_del corruption. prev->next should be ffff8881398a8000, but was 0000000000000000 [ 231.278222] ------------[ cut here ]------------ [ 231.278726] kernel BUG at lib/list_debug.c:53!
