    ext4: fix ABBA deadlock in ext4_xattr_inode_cache_find()

    In the Linux kernel, the following vulnerability has been resolved: ext4: fix ABBA deadlock in ext4_xattr_inode_cache_find() Syzbot/stress-ng reported an ABBA deadlock in ext4 when exercising concurrent xattr workloads (using the ea_inode mount/format option). The deadlock occurs between the running transaction and the eviction thread: - Task 1 (stress-ng): Holds a reference to a shared mbcache_entry (ce) and calls ext4_xattr_inode_cache_find() -> ext4_iget() to retrieve the corresponding EA inode. Since the EA inode is currently being evicted, ext4_iget() blocks in __wait_on_freeing_inode() waiting for eviction to complete. - Task

    ext4: drain in-flight DIO before buffered write fallback

    In the Linux kernel, the following vulnerability has been resolved: ext4: drain in-flight DIO before buffered write fallback generic/746 started failing intermittently on ext3 (no-extent inodes). The test triggers 'Page cache invalidation failure on direct I/O' warnings and subsequent fsync returns -EIO. Adding a 50ms delay between ext4_buffered_write_iter() and filemap_write_and_wait_range() in ext4_dio_write_iter() makes the race almost always reproducible. On no-extent inodes, DIO writes to holes cannot use unwritten extents, so ext4_iomap_alloc() leaves m_flags=0 and ext4_map_blocks() returns 0. The iomap layer then returns -ENOTBLK, c

    ext4: use fsdata to track inline data write state and fix race

    In the Linux kernel, the following vulnerability has been resolved: ext4: use fsdata to track inline data write state and fix race Instead of checking the live inode state (ext4_has_inline_data(inode) and ext4_test_inode_state(inode, EXT4_STATE_MAY_INLINE_DATA)) in the write_end handlers, use the fsdata parameter of the address space operations to explicitly pass down the state in which write_begin prepared the write. A concurrent thread (such as ext4_page_mkwrite()) can convert the inline data to an extent between write_begin and write_end. If this happens, the write_end handlers would previously miss the inline write_end path and fall th

    In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: Avoid buffer overread in ath11k_wmi_tlv_op_rx() Currently, in ath11k_wmi_tlv_op_rx(), the firmware buffer is read without first verifying that the buffer has enough data to hold a header. This could result in a buffer overread. Add an upfront length check before dereferencing skb->data as a wmi_cmd_hdr. The check is placed before the trace_ath11k_wmi_event() call to preserve the existing trace semantics (tracing the full raw WMI event including the header), unlike the analogous ath12k fix which could use skb_pull_data() directly. Compile tested only.

    In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Clear VM_MAYWRITE on DBR/toggle page mmap bnxt_re_mmap() rejects VM_WRITE for the DBR_PAGE and TOGGLE_PAGE mmap flags, but a read-only mapping can still retain VM_MAYWRITE. nd later be upgraded with mprotect(PROT_WRITE). This can bypass the write check that only runs at mmap time. Clear VM_MAYWRITE before vm_insert_page() in the shared DBR/toggle-page branch, matching the existing policy that userspace writes are not expected for these pages.

    ext4: fix buffer_head leak in ext4_init_orphan_info

    In the Linux kernel, the following vulnerability has been resolved: ext4: fix buffer_head leak in ext4_init_orphan_info ext4_init_orphan_info() reads orphan file blocks with ext4_bread() and stores the returned buffer_head in oi->of_binfo[i].ob_bh. If ext4_bread() succeeds but the orphan block magic or checksum validation fails, the function jumps to out_free. However, the old out_free loop starts releasing buffers from i - 1, so the current buffer_head at index i is skipped. This leaks the buffer_head reference obtained by ext4_bread() on the bad magic and bad checksum error paths. Fix this by tracking the number of successfully read bu

    firmware: arm_scmi: Roll back partial protocol table registration

    In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Roll back partial protocol table registration scmi_protocol_table_register() can leave earlier requests registered when a later entry in the same ID table fails. Each request retains a pointer to the driver's ID table, so a failed module load can leave a dangling pointer after the module storage is released. Unrequest only the successfully registered prefix, in reverse order, before returning the failure. Leave the failed entry and the remaining entries untouched because matching requests can be owned by another driver.

    In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Unrequest devices if driver registration fails scmi_driver_register() requests protocol devices before registering the driver. If driver_register() fails, those requests remain in the global IDR and retain pointers to the module's ID table. Once the failed module load releases that storage, later request matching or SCMI device creation can dereference the stale pointers. Unrequest the complete protocol table before returning the registration failure. At this point table registration succeeded, so every entry is owned by the current registration attempt

Return the local_out() result directly, matching the ownership handling in xfrm_output_resume().

    liveupdate: Remember FLB retrieve() status

    In the Linux kernel, the following vulnerability has been resolved: liveupdate: Remember FLB retrieve() status LUO keeps track of successful retrieve attempts on an FLB. It does so to avoid multiple retrievals of the same FLB. Multiple retrievals cause problems because once the FLB is retrieved, the serialized data structures are likely freed and the FLB is likely in a very different state from what the code expects. All this works well when retrieve succeeds. When it fails, luo_flb_retrieve_one() returns the error immediately, without ever storing anywhere that a retrieve was attempted or what its error code was. If the user attempts to r

    In the Linux kernel, the following vulnerability has been resolved: pinctrl: mediatek: use devm_gpiochip_add_data() for GPIO chip The gpio_chip is allocated with device-managed memory but registered with the non-managed gpiochip_add_data(). This was harmless while the drivers were built-in, but once they can be built as modules and unbound/rmmod'd, devm frees the gpio_chip's memory while it is still registered, causing a use-after-free. Register it with devm_gpiochip_add_data() so it shares the same device-managed lifecycle, which also lets the manual gpiochip_remove() error paths go away.
