CVE-2026-63999
In the Linux kernel, the following vulnerability has been resolved:
ethtool: rss: fix indir_table and hkey leak on get_rxfh failure
rss_prepare_get() allocates the indirection table and hash key buffer via rss_get_data_alloc(), then calls ops->get_rxfh() to populate them. If get_rxfh() fails, the function returns an error without freeing the allocation.
