Title
xfs: fix log recovery buffer allocation for the legacy h_size fixup
Summary
In the Linux kernel, the following vulnerability has been resolved: xfs: fix log recovery buffer allocation for the legacy h_size fixup Commit a70f9fe52daa ("xfs: detect and handle invalid iclog size set by mkfs") added a fixup for incorrect h_size values used for the initial umount record in old xfsprogs versions. Later commit 0c771b99d6c9 ("xfs: clean up calculation of LR header blocks") cleaned up the log reover buffer calculation, but stoped using the fixed up h_size value to size the log recovery buffer, which can lead to an out of bounds access when the incorrect h_size does not come from the old mkfs tool, but a fuzzer. Fix this by open coding xlog_logrec_hblks and taking the fixed h_size into account for this calculation.

Equivalently, an unprivileged local user on an automount-enabled system reaches it with PR:L/UI:N, which yields the identical exploitability score.\nUI:R - A user or automount service must mount the malicious filesystem with a dirty log so that `xlog_do_recovery_pass()` runs; the attacker cannot initiate the mount themselves.\nS:U - The out-of-bounds access and its consequences stay inside the kernel\u0027s own security authority \u2014 no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `xlog_cksum()` and `xlog_unpack_data()` read at 32 KB strides up to ~224 KB past a 512-byte `kvzalloc()` slab object, and on a non-CRC (v4) image the harvested heap dwords are copied into the replayed log data and committed to the filesystem, giving the attacker a large, readable kernel heap disclosure.\nI:L - There is no out-of-bounds write \u2014 `dbp` is sized from the fixed-up `h_size` and `bblks \u003c= BTOBB(h_size)` \u2014 but the out-of-bounds kernel heap dwords are spliced into the log record data by `xlog_unpack_data()` and replayed into on-disk metadata, producing limited, attacker-uncontrolled modification of filesystem data.\nA:H - Reading roughly 224 KB beyond a 512-byte slab allocation readily crosses into unmapped memory, producing a page fault/oops (or a KASAN slab-out-of-bounds panic) during mount, taking down the system."
