An update of the linux package has been released.

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - wifimt7601u整数アンダーフローを修正 「mt7601u_rx_skb_from_seg()」での null ポインターデリファレンスにつながる整数アンダーフローを修正します。URB パケットの変数「dma_len」が操作される可能性があり、これにより「mt7601u_rx_process_seg()」の「seg_len」の整数アンダーフローを発生させる可能性があります。このアンダーフローが続いて、「mt7601u_rx_skb_from_seg()」の「bad_frame」チェックがバイパスされ、最終的にポインター「p」の逆参照につながります。これは null ポインターです。「dma_len」が「min_seg_len」より大きいことを確認。syzkaller の修正バージョンによって見つかりました。KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f] CPU: 0 PID: 12 Comm: ksoftirqd/0 Tainted: GWO 5.14.0+ #139 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel- 1.12.1-0-ga5cab58e9a3f-prebuilt.qemu.org04/01/2014 RIP0010:skb_add_rx_frag+0x143/0x370 コードe2 07 83 c2 03 38 ca 7c 08 84 c9 0f 85 86 01 00 4c 8d 48d 89 68 08 48 b8 00 00 00 00 fc ff df 4c 89 fa 48 c1 ea 03 <80> 3c 02 00 0f 85 cd 01 00 00 48 8b 45 08 a8 01 0f 85 3d 01 00 00 RSP: 0018: ffffc900000000000000000000000000000000000000000000000000000000 00010202 RAXdffffc0000000000 RBX

  - wifi: mt7601u: fix an integer underflow Fix an integer underflow that leads to a null pointer dereference     in 'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet could be manipulated, which could     trigger an integer underflow of 'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently     causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be bypassed, eventually leading to a     dereference of the pointer 'p', which is a null pointer. Ensure that 'dma_len' is greater than     'min_seg_len'. Found by a modified version of syzkaller.
