Description
In the Linux kernel, the following vulnerability has been resolved: f2fs: fix kernel crash due to null io->bio We should return when io->bio is null before doing anything. Otherwise, panic. BUG: kernel NULL pointer dereference, address: 0000000000000010 RIP: 0010:__submit_merged_write_cond+0x164/0x240 [f2fs] Call Trace: <TASK> f2fs_submit_merged_write+0x1d/0x30 [f2fs] commit_checkpoint+0x110/0x1e0 [f2fs] f2fs_write_checkpoint+0x9f7/0xf00 [f2fs] ? __pfx_issue_checkpoint_thread+0x10/0x10 [f2fs] __checkpoint_and_complete_reqs+0x84/0x190 [f2fs] ? preempt_count_add+0x82/0xc0 ? __pfx_issue_checkpoint_thread+0x10/0x10 [f2fs] issue_checkpoint_thread+0x4c/0xf0 [f2fs] ? __pfx_autoremove_wake_function+0x10/0x10 kthread+0xff/0x130 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x2c/0x50 </TASK>
A NULL pointer dereference vulnerability has been identified in the Linux kernel's F2FS (Flash-Friendly File System) implementation. This issue arises because the code does not properly check if the I/O structure's bio field is NULL before proceeding with certain operations. As a result, when the bio field is NULL, the kernel experiences a crash due to a NULL pointer dereference. This vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been patched. The specific commit addressing this issue is available in the Linux kernel stable tree.
