{"id":"DEBIAN-CVE-2024-36925","details":"In the Linux kernel, the following vulnerability has been resolved:  swiotlb: initialise restricted pool list_head when SWIOTLB_DYNAMIC=y  Using restricted DMA pools (CONFIG_DMA_RESTRICTED_POOL=y) in conjunction with dynamic SWIOTLB (CONFIG_SWIOTLB_DYNAMIC=y) leads to the following crash when initialising the restricted pools at boot-time:    | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008   | Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP   | pc : rmem_swiotlb_device_init+0xfc/0x1ec   | lr : rmem_swiotlb_device_init+0xf0/0x1ec   | Call trace:   |  rmem_swiotlb_device_init+0xfc/0x1ec   |  of_reserved_mem_device_init_by_idx+0x18c/0x238   |  of_dma_configure_id+0x31c/0x33c   |  platform_dma_configure+0x34/0x80  faddr2line reveals that the crash is in the list validation code:    include/linux/list.h:83   include/linux/rculist.h:79   include/linux/rculist.h:106   kernel/dma/swiotlb.c:306   kernel/dma/swiotlb.c:1695  because add_mem_pool() is trying to list_add_rcu() to a NULL 'mem-\u003epools'.  Fix the crash by initialising the 'mem-\u003epools' list_head in rmem_swiotlb_device_init() before calling add_mem_pool().","modified":"2026-09-15T09:03:14.147653235Z","published":"2024-05-30T16:15:15.800Z","upstream":["CVE-2024-36925"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-36925"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-36925.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-36925.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
