Summary
In the Linux kernel, the following vulnerability has been resolved: netfs: Call `invalidate_cache` only if implemented Many filesystems such as NFS and Ceph do not implement the `invalidate_cache` method. On those filesystems, if writing to the cache (`NETFS_WRITE_TO_CACHE`) fails for some reason, the kernel crashes like this: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor instruction fetch in kernel mode #PF: error_code(0x0010) - not-present page PGD 0 P4D 0 Oops: Oops: 0010 [#1] SMP PTI CPU: 9 UID: 0 PID: 3380 Comm: kworker/u193:11 Not tainted 6.13.3-cm4all1-hp #437 Hardware name: HP ProLiant DL380 Gen9/ProLiant DL380 Gen9, BIOS P89 10/17/2018 Workqueue: events_unbound netfs_write_collection_worker RIP: 0010:0x0 Code: Unable to access opcode bytes at 0xffffffffffffffd6.
