Spectrum-4 has more than \n256 ports, so the register was extended by cited commit with a new \n'port_page' field. \n \nHowever, when filling the register's payload, the driver specifies the \nports as absolute numbers and not relative to the first port of the port \npage, resulting in memory corruptions [1]. \n \nFix by specifying the ports relative to the first port of the port page. \n \n[1] \nBUG: KASAN: slab-use-after-free in mlxsw_sp_sb_occ_snapshot+0xb6d/0xbc0 \nRead of size 1 at addr ffff8881068cb00f by task devlink/1566 \n[...] \nCall Trace: \n \n dump_stack_lvl+0xc6/0x120 \n print_report+0xce/0x670 \n kasan_report+0xd7/0x110 \n mlxsw_sp_sb_occ_snapshot+0xb6d/0xbc0 \n mlxsw_devlink_sb_occ_snapshot+0x75/0xb0 \n devlink_nl_sb_occ_snapshot_doit+0x1f9/0x2a0 \n genl_family_rcv_msg_doit+0x20c/0x300 \n genl_rcv_msg+0x567/0x800 \n netlink_rcv_skb+0x170/0x450 \n genl_rcv+0x2d/0x40 \n netlink_unicast+0x547/0x830 \n netlink_sendmsg+0x8d4/0xdb0 \n __sys_sendto+0x49b/0x510 \n __x64_sys_sendto+0xe5/0x1c0 \n do_syscall_64+0xc1/0x1d0 \n entry_SYSCALL_64_after_hwframe+0x77/0x7f \n[...] \nAllocated by task 1: \n kasan_save_stack+0x33/0x60 \n kasan_save_track+0x14/0x30 \n __kasan_kmalloc+0x8f/0xa0 \n copy_verifier_state+0xbc2/0xfb0 \n do_check_common+0x2c51/0xc7e0 \n bpf_check+0x5107/0x9960 \n bpf_prog_load+0xf0e/0x2690 \n __sys_bpf+0x1a61/0x49d0 \n __x64_sys_bpf+0x7d/0xc0 \n do_syscall_64+0xc1/0x1d0 \n entry_SYSCALL_64_after_hwframe+0x77/0x7f \n \nFreed by task 1: \n kasan_save_stack+0x33/0x60 \n kasan_save_track+0x14/0x30 \n kasan_save_free_info+0x3b/0x60 \n poison_slab_object+0x109/0x170 \n __kasan_slab_free+0x14/0x30 \n kfree+0xca/0x2b0 \n free_verifier_state+0xce/0x270 \n do_check_common+0x4828/0xc7e0 \n bpf_check+0x5107/0x9960 \n bpf_prog_load+0xf0e/0x2690 \n __sys_bpf+0x1a61/0x49d0 \n __x64_sys_bpf+0x7d/0xc0 \n do_syscall_64+0xc1/0x1d0 \n entry_SYSCALL_64_after_hwframe+0x77/0x7f \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n \"Detection Date\": \"29 Jul 2024\",\n \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-07-29T18:48:31.000000Z"} 2024-07-29T18:48:31+00:00
