Title
ext4: fix invalid free tracking in ext4_xattr_move_to_block()
Summary
In the Linux kernel, the following vulnerability has been resolved: ext4: fix invalid free tracking in ext4_xattr_move_to_block() In ext4_xattr_move_to_block(), the value of the extended attribute which we need to move to an external block may be allocated by kvmalloc() if the value is stored in an external inode. So at the end of the function the code tried to check if this was the case by testing entry->e_value_inum. However, at this point, the pointer to the xattr entry is no longer valid, because it was removed from the original location where it had been stored. So we could end up calling kvfree() on a pointer which was not allocated by kvmalloc(); or we could also potentially leak memory by not freeing the buffer when it should be freed. Fix this by storing whether it should be freed in a separate variable.

No network or remote peer is involved.\nAC:L - No race and no memory-layout luck is needed; the invalid free happens deterministically whenever the moved inline-value xattr is followed by an EA-inode-backed entry, and the attacker controls both the entry ordering (name-sorted) and the sizes that drive `ext4_xattr_make_inode_space()`\u0027s selection, or controls everything outright via a crafted image.\nPR:L - An ordinary unprivileged user only needs a file they own to set `user.*` xattrs on and then dirty the inode; no capability, and `ext4_expand_extra_isize_ea()` runs from the ordinary `ext4_mark_inode_dirty()` path.\nUI:N - In the local-user scenario the attacker performs every step themselves \u2014 setxattr, then touch/write to dirty the inode \u2014 with no victim action required.\nS:U - The corruption stays within the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - `__free_pages()` on a still-referenced page-cache page underflows its refcount, so the page is recycled while ext4 keeps reading the inode table through the stale `buffer_head`, disclosing whatever kernel data now occupies that page; the `WARN` also leaks a kernel pointer.\nI:H - After the premature page free, ext4 continues writing inode and xattr bytes into the reallocated page through the stale `buffer_head`, giving a page-granularity kernel write primitive suitable for privilege escalation; slab/memcg accounting is corrupted as well.\nA:H - On 4.19/5.10-era kernels `kfree()` on the non-slab pointer hits `BUG_ON(!PageCompound(page))` for an immediate panic; on 6.x it produces a `WARN_ON_ONCE` (panic under `panic_on_warn`) plus a page refcount underflow that leads to a later oops, and the inverse case leaks memory on every attempt."
