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: refresh inline data size before
 write operations The cached ei->i_inline_size can become stale between the initial size check and when
 ext4_update_inline_data()/ext4_create_inline_data() use it. Although ext4_get_max_inline_size() reads the
 correct value at the time of the check, concurrent xattr operations can modify i_inline_size before
 ext4_write_lock_xattr() is acquired. This causes ext4_update_inline_data() and ext4_create_inline_data()
 to work with stale capacity values, leading to a BUG_ON() crash in ext4_write_inline_data(): kernel BUG at
 fs/ext4/inline.c:1331! BUG_ON(pos + len > EXT4_I(inode)->i_inline_size); The race window: 1.
 ext4_get_max_inline_size() reads i_inline_size = 60 (correct) 2. Size check passes for 50-byte write 3.
 [Another thread adds xattr, i_inline_size changes to 40] 4. ext4_write_lock_xattr() acquires lock 5.
 ext4_update_inline_data() uses stale i_inline_size = 60 6. Attempts to write 50 bytes but only 40 bytes
 actually available 7. BUG_ON() triggers Fix this by recalculating i_inline_size via
 ext4_find_inline_data_nolock() immediately after acquiring xattr_sem. This ensures
 ext4_update_inline_data() and ext4_create_inline_data() work with current values that are protected from
 concurrent modifications. This is similar to commit a54c4613dac1 ("ext4: fix race writing to an
 inline_data file while its xattrs are changing") which fixed i_inline_off staleness. This patch addresses
 the related i_inline_size staleness issue. (CVE-2025-68264)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.439.108 or later.
