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.
