In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: Fix NULL ptr dereference when ENOMEM Do not call snd_dma_free_pages() when snd_dma_alloc_pages() returns -ENOMEM because it leads to a NULL pointer dereference bug. The dmesg says: [ T1387] sof-audio-pci-intel-tgl 0000:00:1f.3: error: memory alloc failed: -12 [ T1387] BUG: kernel NULL pointer dereference, address: 0000000000000000 [ T1387] #PF: supervisor read access in kernel mode [ T1387] #PF: error_code(0x0000) - not-present page [ T1387] PGD 0 P4D 0 [ T1387] Oops: 0000 [#1] PREEMPT SMP NOPTI [ T1387] CPU: 6 PID: 1387 Comm: alsa-sink-HDA A Tainted: G W 5.17.0-rc4-superb-owl-00055-g80d47f5de5e3 [ T1387] Hardware name: HP HP Laptop 14s-dq2xxx/87FD, BIOS F.15 09/15/2021 [ T1387] RIP: 0010:dma_free_noncontiguous+0x37/0x80 [ T1387] Code: [... snip ...] [ T1387] RSP: 0000:ffffc90002b87770 EFLAGS: 00010246 [ T1387] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000000 [ T1387] RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff888101db30d0 [ T1387] RBP: 00000000fffffff4 R08: 0000000000000000 R09: 0000000000000000 [ T1387] R10: 0000000000000000 R11: ffffc90002b874d0 R12: 0000000000000001 [ T1387] R13: 0000000000058000 R14: ffff888105260c68 R15: ffff888105260828 [ T1387] FS: 00007f42e2ffd640(0000) GS:ffff888466b80000(0000) knlGS:0000000000000000 [ T1387] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ T1387] CR2: 0000000000000000 CR3: 000000014acf0003 CR4: 0000000000770ee0 [ T1387] PKRU: 55555554 [ T1387] Call Trace: [ T1387] [ T1387] cl_stream_prepare+0x10a/0x120 [snd_sof_intel_hda_common 146addf995b9279ae7f509621078cccbe4f875e1] [... snip ...] [ T1387]
