CVE-2024-44997

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtk_wed: fix use-after-free panic in mtk_wed_setup_tc_block_cb() When there are multiple ap interfaces on one band and with WED on, turning the interface down will cause a kernel panic on MT798X. Previously, cb_priv was freed in mtk_wed_setup_tc_block() without marking NULL,and mtk_wed_setup_tc_block_cb() didn't check the value, too. Assign NULL after free cb_priv in mtk_wed_setup_tc_block() and check NULL in mtk_wed_setup_tc_block_cb(). ---------- Unable to handle kernel paging request at virtual address 0072460bca32b4f5 Call trace: mtk_wed_setup_tc_block_cb+0x4/0x38 0xffffffc0794084bc tcf_block_playback_offloads+0x70/0x1e8 tcf_block_unbind+0x6c/0xc8 ... ---------

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: ethernet: mtk_wed: arregla el pánico de use after free en mtk_wed_setup_tc_block_cb() Cuando hay múltiples interfaces de punto de acceso en una banda y con WED activado, desactivar la interfaz provocará un pánico de kernel en MT798X. Anteriormente, cb_priv se liberaba en mtk_wed_setup_tc_block() sin marcar NULL, y mtk_wed_setup_tc_block_cb() tampoco verificaba el valor. Asigna NULL después de liberar cb_priv en mtk_wed_setup_tc_block() y marca NULL en mtk_wed_setup_tc_block_cb(). ---------- No se puede manejar la solicitud de paginación del núcleo en la dirección virtual 0072460bca32b4f5 Seguimiento de llamadas: mtk_wed_setup_tc_block_cb+0x4/0x38 0xffffffc0794084bc tcf_block_playback_offloads+0x70/0x1e8 tcf_block_unbind+0x6c/0xc8 ... ---------
