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: f2fs: fix to trigger foreground gc
 during f2fs_map_blocks() in lfs mode w/ "mode=lfs" mount option, generic/299 will cause system panic as
 below: ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.c:2835! Call Trace: <TASK>

 entry_SYSCALL_64_after_hwframe+0x76/0x7e RIP: 0010:new_curseg+0x70f/0x720 The root cause of we run out-of-
 space is: in f2fs_map_blocks(), f2fs may trigger foreground gc only if it allocates any physical block, it
 will be a little bit later when there is multiple threads writing data w/ aio/dio/bufio method in
 parallel, since we always use OPU in lfs mode, so f2fs_map_blocks() does block allocations aggressively.
 In order to fix this issue, let's give a chance to trigger foreground gc in prior to block allocation in
 f2fs_map_blocks(). (CVE-2025-38626)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
