In the Linux kernel, the following vulnerability has been resolved:
isofs: Prevent the use of too small fid
syzbot reported a slab-out-of-bounds Read in isofs_fh_to_parent. [1]
The handle_bytes value passed in by the reproducing program is equal to 12.
In handle_to_path(), only 12 bytes of memory are allocated for the structure
file_handle->f_handle member, which causes an out-of-bounds access when
accessing the member parent_block of the structure isofs_fid in isofs,
because accessing parent_block requires at least 16 bytes of f_handle.
Here, fh_len is used to indirectly confirm that the value of handle_bytes
is greater than 3 before accessing parent_block.

isofs: validate block number from NFS file handle in isofs_export_iget
isofs_fh_to_dentry() and isofs_fh_to_parent() pass an attacker-

CVE-2025-37780 [HIGH] isofs: Prevent the use of too small fid
isofs: Prevent the use of too small fid
FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

CVE-2025-37780 [HIGH] kernel: isofs: Prevent the use of too small fid
kernel: isofs: Prevent the use of too small fid
In the Linux kernel, the following vulnerability has been resolved:
isofs: Prevent the use of too small fid
syzbot reported a slab-out-of-bounds Read in isofs_fh_to_parent. [1]
The handle_bytes value passed in by the reproducing program is equal to 12.
In handle_to_path(), only 12 bytes of memory are allocated for the structure
file_handle->f_handle member, which causes an out-of-bounds access when
accessing the member parent_block of the structure isofs_fid in isofs,
because accessing parent_block requires at least 16 bytes of f_handle.
Here, fh_len is used to indirectly confirm that the value of handle_bytes
is greater than 3 before accessing parent_block.

CVE-2026-46124 [HIGH] CVE-2026-46124 kernel: isofs: validate block number from NFS file handle in isofs_export_iget
CVE-2026-46124 kernel: isofs: validate block number from NFS file handle in isofs_export_iget
In the Linux kernel, the following vulnerability has been resolved:
isofs: validate block number from NFS file handle in isofs_export_iget
isofs_fh_to_dentry() and isofs_fh_to_parent() pass an attacker-
controlled block number (ifid->block or ifid->parent_block) from
the NFS file handle to isofs_export_iget(), which only rejects
block == 0 before calling isofs_iget() and ultimately sb_bread().
A crafted file handle with fh_len sufficient to pass the check
added by commit 0405d4b63d08 ("isofs: Prevent the use of too small
fid") can still drive the server to read any in-range block on the
backing device as if it were an iso_directory_record. That earlier
fix was assigned CVE-2025-37780.
