At 4k block size, the length of the s_mb_avg_fragment_size list is 14, but an oversized s_mb_group_prealloc is set, causing slab-out-of-bounds to be triggered by an attempt to access an element at index 29. Add a new attr_id attr_clusters_in_group with values in the range [0, sbi->s_clusters_per_group] and declare mb_group_prealloc as that type to fix the issue. In addition avoid returning an order from mb_avg_fragment_size_order() greater than MB_NUM_ORDERS(sb) and reduce some useless loops.

The value returned from acpi_find_last_cache_level() is then assigned to unsigned fw_level.

[PATCH OLK-6.6] mucse: rnpm: fix UAF in rnpm_remove()
by Ding Hui 04 Jul '25

04 Jul '25

driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICJVFM CVE: NA ------------------------------------ KASAN report a use-after-free case in rnpm_remove(). The pf_adapter is already be freed in rnpm_rm_pf_adapter(), but using pf_adapter->hw.mbx after that. Fix it by moving the dma_free_coherent() into rnpm_rm_pf_adapter() just before releasing pf_adapter, that also fix reply_dma leaking on rnpm_probe() error path.
