远程 CentOS Linux 9 主机上安装的多个程序包受到 kernel-5.14.0-539.el9 版本变更日志中提及的多个漏洞影响。

  - 已修复 Linux 内核中的下列漏洞：Bluetooth: MGMT: Fix possible crash on mgmt_index_removed If mgmt_index_removed is called while there are commands queued on cmd_sync it could lead to crashes like the bellow trace: 0x0000053D: __list_del_entry_valid_or_report+0x98/0xdc 0x0000053D:
    mgmt_pending_remove+0x18/0x58 [bluetooth] 0x0000053E: mgmt_remove_adv_monitor_complete+0x80/0x108 [bluetooth] 0x0000053E: hci_cmd_sync_work+0xbc/0x164 [bluetooth] So while handling mgmt_index_removed this attempts to dequeue commands passed as user_data to cmd_sync. (CVE-2024-49951)

  - 已修复 Linux 内核中的下列漏洞：sctp: properly validate chunk size in sctp_sf_ootb() A size validation fix similar to that in Commit 50619dbf8db7 (sctp: add size validation when walking chunks) is also required in sctp_sf_ootb() to address a crash reported by syzbot: BUG:
    KMSAN: uninit-value in sctp_sf_ootb+0x7f5/0xce0 net/sctp/sm_statefuns.c:3712 sctp_sf_ootb+0x7f5/0xce0 net/sctp/sm_statefuns.c:3712 sctp_do_sm+0x181/0x93d0 net/sctp/sm_sideeffect.c:1166 sctp_endpoint_bh_rcv+0xc38/0xf90 net/sctp/endpointola.c:407 sctp_inq_push+0x2ef/0x380 net/sctp/inqueue.c:88 sctp_rcv+0x3831/0x3b20 net/sctp/input.c:243 sctp4_rcv+0x42/0x50 net/sctp/protocol.c:1159 ip_protocol_deliver_rcu+0xb51/0x13d0 net/ipv4/ip_input.c:205 ip_local_deliver_finish+0x336/0x500 net/ipv4/ip_input.c:233 (CVE-2024-50299)

  - kernelntbintel修复 debugfs_create_dir() 的 NULL 与 IS_ERR() 缺陷 (CVE-2023-52917)
