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

wifi: brcmfmac: Check the return value of of_property_read_string_index()

Somewhen between 6.10 and 6.11 the driver started to crash on my MacBookPro14,3. The property doesn't exist and 'tmp' remains uninitialized, so we pass a random pointer to devm_kstrdup().

The crash I am getting looks like this:

OESA-2025-1320 — kernel security update

Affected: openEuler:24.03-LTS: kernel

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

RDMA/rtrs: Ensure 'ib_sge list' is accessible

Move the declaration of the 'ib_sge list' variable outside the 'always_invalidate' block to ensure it remains accessible for use throughout the function.

Previously, 'ib_sge list' was declared within the 'always_invalidate' block, limiting its accessibility, then caused a 'BUG: kernel NULL pointer dereference'[1]. ? __die_body.cold+0x19/0x27 ? page_fault_oops+0x15a/0x2d0 ? search_module_extables+0x19/0x60 ? search_bpf_extables+0x5f/0x80 ? exc_page_fault+0x7e/0x180 ? asm_exc_page_fault+0x26/0x30 ? memcpy_orig+0xd5/0x140 rxe_mr_copy+0x1c3/0x200 [rdma_rxe] ? rxe_pool_get_index+0x4b/0x80 [rdma_rxe] copy_data+0xa5/0x230 [rdma_rxe] rxe_requester+0xd9b/0xf70 [rdma_rxe] ? finish_task_switch.isra.0+0x99/0x2e0 rxe_sender+0x13/0x40 [rdma_rxe] do_task+0x68/0x1e0 [rdma_rxe] process_one_work+0x177/0x330 worker_thread+0x252/0x390 ? __pfx_worker_thread+0x10/0x10

This change ensures the variable is available for subsequent operations that require it.
