Title
isofs: Fix out of bound access for corrupted isofs image
Summary
In the Linux kernel, the following vulnerability has been resolved:
isofs: Fix out of bound access for corrupted isofs image

A remote NFS client can therefore reach the bug over the network on a host that exports an iso9660 mount.\nAC:L - The attacker fully controls the NFS filehandle block/offset and can aim at a byte near a buffer boundary whose length field is below sizeof(struct iso_directory_record), reliably taking the undersized de_len path. No race or layout outside attacker influence is required.\nPR:N - In the highest-severity reasonable deployment, an iso9660 tree is NFS-exported with unauthenticated or otherwise unprivileged client access (common sec=sys/media-server setups). The remote attacker needs no privileges on the NFS server host.\nUI:N - Once the iso9660 filesystem is exported, the attacker triggers isofs_read_inode by sending NFS requests with a crafted filehandle. No separate victim action such as mounting or opening a file is required at exploit time.\nS:U - The out-of-bounds read occurs in the same kernel authority that runs nfsd/isofs. This is not a VM escape, IOMMU bypass, or other cross-scope boundary violation.\nC:H - With de_len smaller than the directory-record struct, isofs_read_inode reads past a kmalloc(de_len) buffer or past bh-\u003eb_data; syzbot reported a KASAN use-after-free read in this path. That over-read can disclose adjacent kernel memory and can also surface through inode fields returned over NFS.\nI:N - The defect is an out-of-bounds read of directory-entry fields into inode metadata, not an out-of-bounds write or other memory-modification primitive. No integrity impact beyond interpreting over-read bytes as ISO metadata is indicated.\nA:H - The same invalid read was shown to fault under KASAN and can oops when it touches freed or unmapped memory beyond the undersized object or buffer_head. A remote client can repeat crafted filehandle lookups to cause a high-impact denial of service."
