In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: fix wrong fallback logic for FDIR<br /> <br /> When adding a FDIR filter, if ice_vc_fdir_set_irq_ctx returns failure,<br /> the inserted fdir entry will not be removed and if ice_vc_fdir_write_fltr<br /> returns failure, the fdir context info for irq handler will not be cleared<br /> which may lead to inconsistent or memory leak issue. This patch refines<br /> failure cases to resolve this issue.
