      "title": "ASoC: meson: Keep link pointers valid on realloc failure",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: meson: Keep link pointers valid on realloc failure\n\nmeson_card_reallocate_links() grows the DAI link and private data\narrays with two consecutive krealloc() calls and updates the owner\npointers only after both calls have succeeded.\n\nA successful krealloc() may move the data: it frees the old block and\nreturns a new one. When that happens for the link array and the second\nkrealloc() then fails, card->dai_link still points to the block that\nkrealloc() already freed, and the error path frees the new block too.\nThe probe error path then calls meson_card_clean_references(), which\ndereferences card->dai_link and kfree()s it again, resulting in a\nuse-after-free and a double free.\n\nCommit card->dai_link and card->num_links right after the first\nkrealloc() succeeds, so the pointer always refers to a valid allocation\nthat meson_card_clean_references() can walk and free. krealloc() with\n__GFP_ZERO zero-initializes the added entries, so walking them on the\nerror path is safe. With both failure paths reduced to a plain return,\ndrop the goto labels and the error message.",
