{"id":"DEBIAN-CVE-2023-54044","details":"In the Linux kernel, the following vulnerability has been resolved:  spmi: Add a check for remove callback when removing a SPMI driver  When removing a SPMI driver, there can be a crash due to NULL pointer dereference if it does not have a remove callback defined. This is one such call trace observed when removing the QCOM SPMI PMIC driver:   dump_backtrace.cfi_jt+0x0/0x8  dump_stack_lvl+0xd8/0x16c  panic+0x188/0x498  __cfi_slowpath+0x0/0x214  __cfi_slowpath+0x1dc/0x214  spmi_drv_remove+0x16c/0x1e0  device_release_driver_internal+0x468/0x79c  driver_detach+0x11c/0x1a0  bus_remove_driver+0xc4/0x124  driver_unregister+0x58/0x84  cleanup_module+0x1c/0xc24 [qcom_spmi_pmic]  __do_sys_delete_module+0x3ec/0x53c  __arm64_sys_delete_module+0x18/0x28  el0_svc_common+0xdc/0x294  el0_svc+0x38/0x9c  el0_sync_handler+0x8c/0xf0  el0_sync+0x1b4/0x1c0  If a driver has all its resources allocated through devm_() APIs and does not need any other explicit cleanup, it would not require a remove callback to be defined. Hence, add a check for remove callback presence before calling it when removing a SPMI driver.","modified":"2026-09-15T08:47:38.652086789Z","published":"2025-12-24T13:16:06.030Z","upstream":["CVE-2023-54044"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54044"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.37-1"}]}],"versions":["6.1.27-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54044.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54044.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54044.json"}}],"schema_version":"1.9.0"}
