  - In the Linux kernel, the following vulnerability has been resolved: dma-debug: don't call
    __dma_entry_alloc_check_leak() under free_entries_lock __dma_entry_alloc_check_leak() calls into printk ->     serial console output (qcom geni) and grabs port->lock under free_entries_lock spin lock, which is a     reverse locking dependency chain as qcom_geni IRQ handler can call into dma-debug code and grab     free_entries_lock under port->lock. Move __dma_entry_alloc_check_leak() call out of free_entries_lock     scope so that we don't acquire serial console's port->lock under it.

  - In the Linux kernel, the following vulnerability has been resolved: net/sched: act_mirred: use the backlog     for mirred ingress The test Davide added in commit ca22da2fbd69 (act_mirred: use the backlog for nested     calls to mirred ingress) hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv ->     tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that     if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which     generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks     is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress ->     ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the     backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround     does not seem to address the issue. (CVE-2024-26740)

  - In the Linux kernel, the following vulnerability has been resolved: mm/vmscan: fix a bug calling     wakeup_kswapd() with a wrong zone index With numa balancing on, when a numa system is running where a numa     node doesn't have its local memory so it has no managed zones, the following oops has been observed. It's     because wakeup_kswapd() is called with a wrong zone index, -1. Fixed it by checking the index before     calling wakeup_kswapd(). > BUG: unable to handle page fault for address: 00000000000033f3 > #PF:

  - In the Linux kernel, the following vulnerability has been resolved: vfs: Don't evict inode under the inode     lru traversing context The inode reclaiming process(See function prune_icache_sb) collects all reclaimable     inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try     getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by     function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode     lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru     traversing context, deadlock problems may happen. Case 1: In function ext4_evict_inode(), the ea inode     lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting     context like this: 1. File A has inode i_reg and an ea inode i_ea 2. getfattr(A, xattr_buf) // i_ea is     added into lru // lru->i_ea 3. Then, following three processes running like this: PA PB echo 2 >     /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg     prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state     inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink =     0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode     ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast
    __wait_on_freeing_inode(i_ea) ---- AA deadlock dispose_list // cannot be executed by prune_icache_sb     wake_up_bit(&i_ea->i_state) Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file     deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode     reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting     function), then an ABBA deadlock problem would happen as following: 1. File A has inode ia and a     xattr(with inode ixa), regular file B has inode ib and a xattr. 2. getfattr(A, xattr_buf) // ixa is added     into lru // lru->ixa 3. Then, following three processes running like this: PA PB PC echo 2 >     /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia     prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state     inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0 rm     file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia)     make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast
    __wait_on_freeing_inode(ixa) | iput(ib) // ib->nlink is 0, do evict | ubifs_evict_inode |     ubifs_jnl_delete_inode(ib)  ubifs_jnl_write_inode ABBA deadlock -----make_reservation(BASEHD)     dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&ixa->i_state) Fix the possible deadlock     by using new inode state flag I_LRU_ISOLATING to pin the inode in memory while inode_lru_isolate(
