Description OSIDB Bzimport 2026-08-10 12:34:59 UTC

In the Linux kernel, the following vulnerability has been resolved:

firmware: stratix10-svc: fix memory leaks and list corruption bugs

Fix a memory leak when gen_pool_alloc() fails by freeing pmem on the error
path. Switch pmem allocation from devm_kzalloc() to kzalloc() with
explicit kfree() in the free path to match its list-managed lifetime.
Remove the erroneous list_del(&svc_data_mem) which corrupted the list head
on failed lookups.
