- Summary
- CVE-2026-74595 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
fscrypt: use the mount idmap for the owner check in fscryptioctlset_policy()
fscryptioctlsetpolicy() calls inodeownerorcapable() with &nopmntidmap before allowing an encryption policy to be set, instead of the idmap of the mount the ioctl was issued on.
fscrypt is used by filesystems that support idmapped mounts (e.g. ext4, f2fs), so on such a mount this compares the caller's fsuid against the unmapped on-disk owner rather than the mapped owner: the actual owner can be wrongly denied with -EACCES and an unrelated caller wrongly allowed. Use filemntidmap(filp) instead.
