{"id":"CVE-2024-50298","summary":"net: enetc: allocate vf_state during PF probes","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":"2026-05-18T05:56:10.401519216Z","published":"2024-11-19T01:30:46.029Z","related":["SUSE-SU-2024:4314-1","SUSE-SU-2024:4315-1","SUSE-SU-2024:4316-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4376-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50298.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/35668e29e979b3a1927d3959cdd87327afd8e5eb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7eb923f8d4819737c07d6a8d0daef0a4d7f99e0c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e15c5506dd39885cd047f811a64240e2e8ab401b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef0edfbe9eeed1fccad7cb705648af5222664944"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50298.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50298"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d4fd0404c1c95b17880f254ebfee3485693fa8ba"},{"fixed":"35668e29e979b3a1927d3959cdd87327afd8e5eb"},{"fixed":"ef0edfbe9eeed1fccad7cb705648af5222664944"},{"fixed":"7eb923f8d4819737c07d6a8d0daef0a4d7f99e0c"},{"fixed":"e15c5506dd39885cd047f811a64240e2e8ab401b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-50298.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.1.0"},{"fixed":"6.1.167"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.61"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.11.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-50298.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"}]}
