Title
cachefiles: fix slab-use-after-free in cachefiles_withdraw_cookie()
Summary
In the Linux kernel, the following vulnerability has been resolved: cachefiles: fix slab-use-after-free in cachefiles_withdraw_cookie() We got the following issue in our fault injection stress test: ================================================================== BUG: KASAN: slab-use-after-free in cachefiles_withdraw_cookie+0x4d9/0x600 Read of size 8 at addr ffff888118efc000 by task kworker/u78:0/109 CPU: 13 PID: 109 Comm: kworker/u78:0 Not tainted 6.8.0-dirty #566 Call Trace: <TASK> kasan_report+0x93/0xc0 cachefiles_withdraw_cookie+0x4d9/0x600 fscache_cookie_state_machine+0x5c8/0x1230 fscache_cookie_worker+0x91/0x1c0 process_one_work+0x7fa/0x1800 [...] Allocated by task 117: kmalloc_trace+0x1b3/0x3c0 cachefiles_acquire_volume+0xf3/0x9c0 fscache_create_volume_work+0x97/0x150 process_one_work+0x7fa/0x1800 [...] Freed by task 120301: kfree+0xf1/0x2c0 cachefiles_withdraw_cache+0x3fa/0x920 cachefiles_put_unbind_pincount+0x1f6/0x250 cachefiles_daemon_release+0x13b/0x290 __fput+0x204/0xa00 task_work_run+0x139/0x230 do_exit+0x87a/0x29b0 [...] ================================================================== Following is the process that triggers the issue: p1 | p2 ------------------------------------------------------------ fscache_begin_lookup fscache_begin_volume_access fscache_cache_is_live(fscache_cache) cachefiles_daemon_release cachefiles_put_unbind_pincount cachefiles_daemon_unbind cachefiles_withdraw_cache fscache_withdraw_cache fscache_set_cache_state(cache, FSCACHE_CACHE_IS_WITHDRAWN); cachefiles_withdraw_objects(cache) fscache_wait_for_objects(fscache) atomic_read(&fscache_cache->object_count) == 0 fscache_perform_lookup cachefiles_lookup_cookie cachefiles_alloc_object refcount_set(&object->ref, 1); object->volume = volume fscache_count_object(vcookie->cache); atomic_inc(&fscache_cache->object_count) cachefiles_withdraw_volumes cachefiles_withdraw_volume fscache_withdraw_volume __cachefiles_free_volume kfree(cachefiles_volume) fscache_cookie_state_machine cachefiles_withdraw_cookie cache = object->volume->cache; // cachefiles_volume UAF !!! After setting FSCACHE_CACHE_IS_WITHDRAWN, wait for all the cookie lookups to complete first, and then wait for fscache_cache->object_count == 0 to avoid the cookie exiting after the volume has been freed and triggering the above issue. Therefore call fscache_withdraw_volume() before calling cachefiles_withdraw_objects(). This way, after setting FSCACHE_CACHE_IS_WITHDRAWN, only the following two cases will occur: 1) fscache_begin_lookup fails in fscache_begin_volume_access(). 2) fscache_withdraw_volume() will ensure that fscache_count_object() has been executed before calling fscache_wait_for_objects().

No remote peer data reaches `cachefiles_withdraw_cookie()`, so this requires local access.\nAC:L - The attacker fully drives the racing side by keeping a flood of cookie lookups in flight (repeated opens of uncached files on the fscache-backed mount), so the narrow window between `fscache_wait_for_objects()` and `cachefiles_withdraw_volumes()` is reliably occupied; heap grooming of the 4KB slab is likewise attacker-controlled.\nPR:L - Triggering the lookup side needs only an unprivileged local user with read access to an fscache-enabled netfs or erofs-over-fscache mount \u2014 `__fscache_use_cookie()` is invoked on ordinary file open with no capability check.\nUI:N - No victim action is required; the attacker\u0027s own file opens generate the cookie lookups, and the cache withdrawal is a routine daemon-lifecycle event.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The slab-use-after-free reads `object-\u003evolume-\u003ecache` from a freed kmalloc-4k object, and the resulting pointer is dereferenced repeatedly, letting an attacker who reclaims the slab redirect reads to arbitrary kernel memory and disclose it.\nI:H - The stale `cache` pointer is used for `spin_lock(\u0026cache-\u003eobject_list_lock)` and `override_creds(cache-\u003ecache_cred)` in `cachefiles_begin_secure()`, giving both an arbitrary-address write and attacker-chosen credential installation \u2014 a direct path to privilege escalation.\nA:H - Even unexploited, the use-after-free dereferences garbage in a workqueue context (`fscache_cookie_worker`), producing an oops or panic as shown by the KASAN report."
