Ubuntu.comUB:CVE-2024-26955CVE-2024-26955
In the Linux kernel, the following vulnerability has been resolved: nilfs2:
prevent kernel bug at submit_bh_wbc() Fix a bug where nilfs_get_block()
returns a successful status when searching and inserting the specified
block both fail inconsistently. If this inconsistent behavior is not due to
a previously fixed bug, then an unexpected race is occurring, so return a
temporary error -EAGAIN instead. This prevents callers such as
__block_write_begin_int() from requesting a read into a buffer that is not
mapped, which would cause the BUG_ON check for the BH_Mapped flag in
submit_bh_wbc() to fail.
