{"id":"CVE-2026-80655","summary":"soc: xilinx: Fix race condition in event registration","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsoc: xilinx: Fix race condition in event registration\n\nThe zynqmp_power driver registers handlers for suspend and subsystem\nrestart events using register_event(). However, the work structures\n(zynqmp_pm_init_suspend_work and zynqmp_pm_init_restart_work) used by\nthese handlers were allocated and initialized after the registration\ncall.\n\nThis created a race window where, if the firmware triggered an event\nimmediately after registration but before allocation, the callback\n(suspend_event_callback or subsystem_restart_event_callback) would\ndereference a NULL pointer in work_pending(), leading to a crash.\n\nFix this by allocating and initializing the work structures before\nregistering the events.","modified":"2026-08-30T03:47:21.722056822Z","published":"2026-08-28T06:49:01.988Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80655.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/d349aa118ff5e4cab88424ce1b16e08edd70f8bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb445935338405110baca8f541a2df3b4cb8d712"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80655.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80655"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"fcf544ac64397776a18246eba5a8ca72a47c4405"},{"fixed":"d349aa118ff5e4cab88424ce1b16e08edd70f8bb"},{"fixed":"fb445935338405110baca8f541a2df3b4cb8d712"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80655.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80655.json"}}],"schema_version":"1.9.0"}
