CVE-2026-72375
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: afs: Fix reinitialisation of the inode, in particular ->lock_work It seems that initalising afs_vnode::lock_work a single time in the slab's init function isn't sufficient for work_structs. This results in the DEBUG_OBJECTS debugging stuff producing a warning occasionally when running the generic/131 xfstest: ODEBUG: activate not available (active state 0) object: 0000000016d8760f object type: work_struct hint: afs_lock_work+0x0/0x220 WARNING: lib/debugobjects.c:629 at debug_print_object+0x4b/0x90, CPU#3: locktest/7695 ...

Also, flush ->lock_work when the inode is being evicted to make sure it's not still running.
