CVE-2024-53235
In the Linux kernel, the following vulnerability has been resolved: erofs: fix file-backed mounts over FUSE syzbot reported a null-ptr-deref in fuse_read_args_fill: fuse_read_folio+0xb0/0x100 fs/fuse/file.c:905 filemap_read_folio+0xc6/0x2a0…
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description

Anyway, those use cases need to be supported too. [1] https://docs.kernel.org/filesystems/vfs.html
