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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/soc/xilinx/zynqmp_power.c"],"versions":[{"version":"fcf544ac64397776a18246eba5a8ca72a47c4405","lessThan":"d349aa118ff5e4cab88424ce1b16e08edd70f8bb","status":"affected","versionType":"git"},{"version":"fcf544ac64397776a18246eba5a8ca72a47c4405","lessThan":"fb445935338405110baca8f541a2df3b4cb8d712","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/soc/xilinx/zynqmp_power.c"],"versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d349aa118ff5e4cab88424ce1b16e08edd70f8bb"},{"url":"https://git.kernel.org/stable/c/fb445935338405110baca8f541a2df3b4cb8d712"}],"title":"soc: xilinx: Fix race condition in event registration","x_generator":{"engine":"bippy-1.2.0"}}}}
