{"id":"CVE-2026-89895","published":"2026-09-16T11:16:58.270","lastModified":"2026-09-16T11:16:58.270","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: cobalt: Avoid freeing ALSA private data twice\n\nsnd_cobalt_card_create() stores cobsc in sc->private_data and installs\nsnd_cobalt_card_private_free() as sc->private_free. From that point,\nsnd_card_free(sc) releases cobsc through the ALSA card cleanup path.\n\nIf cobalt_alsa_init() fails after snd_cobalt_card_create(), the\nerr_exit_free path calls snd_card_free(sc) and then kfree(cobsc). That\nsecond free releases the same object again.\n\nRemove the explicit kfree(cobsc) and leave ownership with the ALSA card.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3a7d6b9c4cb5ac18cbd3f1c7f8c7b159c42ba0b1","tags":[]},{"url":"https://git.kernel.org/stable/c/42e00371f83c3fc7b99a36bf0229c74ad5d3c7d8","tags":[]},{"url":"https://git.kernel.org/stable/c/61dfa8ded5efc3a25d331fa9ce5cebb85531fe70","tags":[]},{"url":"https://git.kernel.org/stable/c/6cbc8a73b3464ebeccc49987b7233b6b087b8504","tags":[]},{"url":"https://git.kernel.org/stable/c/75bbf45e3a954e292ae26832d2df40ca2e3ee452","tags":[]},{"url":"https://git.kernel.org/stable/c/8c6610e230b9355cf7df5a338a0592c0f088c00b","tags":[]},{"url":"https://git.kernel.org/stable/c/cb1218da234ea15fa14d90e2d049d686874d7aa3","tags":[]},{"url":"https://git.kernel.org/stable/c/fe65028ee72a7e07e572b351891bd7a1f8917d33","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
