Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: ext4: fix kernel BUG in
ext4_write_inline_data_end When the data=journal mount option is used, the ext4_journalled_write_end()
function incorrectly calls ext4_write_inline_data_end() without checking if the EXT4_STATE_MAY_INLINE_DATA
flag is still set on the inode. If a previous attempt to convert the inline data to an extent failed (e.g.
due to ENOSPC), the EXT4_STATE_MAY_INLINE_DATA flag is cleared, but the EXT4_INODE_INLINE_DATA flag
remains set. In this scenario, the next call to ext4_write_begin() will not prepare the inline data xattr
for writing, but ext4_journalled_write_end() will incorrectly attempt to write to it, triggering a
BUG_ON(pos + len > EXT4_I(inode)->i_inline_size) in ext4_write_inline_data() since i_inline_size was not
expanded. Fix this by ensuring that ext4_journalled_write_end() only calls ext4_write_inline_data_end() if
the EXT4_STATE_MAY_INLINE_DATA flag is set, mirroring the behavior of ext4_write_end() and
ext4_da_write_end(). (CVE-2026-74308)

Solution
