In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: Fix configfs group list head handling Doing a list_del() on the epf_group field of struct pci_epf_driver in pci_epf_remove_cfs() is not correct as this field is a list head, not a list entry. This list_del() call triggers a KASAN warning when an endpoint function driver which has a configfs attribute group is torn down: ================================================================== BUG: KASAN: slab-use-after-free in pci_epf_remove_cfs+0x17c/0x198 Write of size 8 at addr ffff00010f4a0d80 by task rmmod/319 CPU: 3 UID: 0 PID: 319 Comm: rmmod Not tainted 6.16.0-rc2 #1 NONE Hardware name: Radxa ROCK 5B (DT) Call trace: show_stack+0x2c/0x84 (C) dump_stack_lvl+0x70/0x98 print_report+0x17c/0x538 kasan_report+0xb8/0x190 __asan_report_store8_noabort+0x20/0x2c pci_epf_remove_cfs+0x17c/0x198 pci_epf_unregister_driver+0x18/0x30 nvmet_pci_epf_cleanup_module+0x24/0x30 [nvmet_pci_epf] __arm64_sys_delete_module+0x264/0x424 invoke_syscall+0x70/0x260 el0_svc_common.constprop.0+0xac/0x230 do_el0_svc+0x40/0x58 el0_svc+0x48/0xdc el0t_64_sync_handler+0x10c/0x138 el0t_64_sync+0x198/0x19c ...
