CVE-2024-44959

In the Linux kernel, the following vulnerability has been resolved: tracefs: Use generic inode RCU for synchronizing freeing With structure layout randomization enabled for 'struct inode' we need to avoid overlapping any of the RCU-used / initialized-only-once members, e.g. i_lru or i_sb_list to not corrupt related list traversals when making use of the rcu_head.

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().

Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique() with nice analysis.

Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's sk_refcnt after putting it into ehash and releasing the bucket lock.

Thus, there is a small race window where other threads could try to reuse the port during connect() and call sock_hold() in tcp_twsk_unique() for the TIME-WAIT socket with zero refcnt.

If that happens, the refcnt taken by tcp_twsk_unique() is overwritten and sock_put() will cause underflow, triggering a real use-after-free somewhere else.

To avoid the use-after-free, we need to use refcount_inc_not_zero() in tcp_twsk_unique() and give up on reusing the port if it returns false.

[0]: refcount_t: addition on 0; use-after-free.

This patch changes the handling and lifecycle of vm->task_info object. The major changes are:

• vm->task_info is a dynamically allocated ptr now, and its uasge is reference counted.
• introducing two new helper funcs for task_info lifecycle management
  • amdgpu_vm_get_task_info: reference counts up task_info before returning this info -…
