{"id":"AZL-53781","summary":"CVE-2024-50298 affecting package kernel 5.15.200.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: enetc: allocate vf_state during PF probes\n\nIn the previous implementation, vf_state is allocated memory only when VF\nis enabled. However, net_device_ops::ndo_set_vf_mac() may be called before\nVF is enabled to configure the MAC address of VF. If this is the case,\nenetc_pf_set_vf_mac() will access vf_state, resulting in access to a null\npointer. The simplified error log is as follows.\n\nroot@ls1028ardb:~# ip link set eno0 vf 1 mac 00:0c:e7:66:77:89\n[  173.543315] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000004\n[  173.637254] pc : enetc_pf_set_vf_mac+0x3c/0x80 Message from sy\n[  173.641973] lr : do_setlink+0x4a8/0xec8\n[  173.732292] Call trace:\n[  173.734740]  enetc_pf_set_vf_mac+0x3c/0x80\n[  173.738847]  __rtnl_newlink+0x530/0x89c\n[  173.742692]  rtnl_newlink+0x50/0x7c\n[  173.746189]  rtnetlink_rcv_msg+0x128/0x390\n[  173.750298]  netlink_rcv_skb+0x60/0x130\n[  173.754145]  rtnetlink_rcv+0x18/0x24\n[  173.757731]  netlink_unicast+0x318/0x380\n[  173.761665]  netlink_sendmsg+0x17c/0x3c8","modified":"2026-04-01T05:16:36.193644Z","published":"2024-11-19T02:16:31Z","upstream":["CVE-2024-50298"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50298"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-53781.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
