{"id":"CVE-2024-53091","summary":"bpf: Add sk_is_inet and IS_ICSK check in tls_sw_has_ctx_tx/rx","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Add sk_is_inet and IS_ICSK check in tls_sw_has_ctx_tx/rx\n\nAs the introduction of the support for vsock and unix sockets in sockmap,\ntls_sw_has_ctx_tx/rx cannot presume the socket passed in must be IS_ICSK.\nvsock and af_unix sockets have vsock_sock and unix_sock instead of\ninet_connection_sock. For these sockets, tls_get_ctx may return an invalid\npointer and cause page fault in function tls_sw_ctx_rx.\n\nBUG: unable to handle page fault for address: 0000000000040030\nWorkqueue: vsock-loopback vsock_loopback_work\nRIP: 0010:sk_psock_strp_data_ready+0x23/0x60\nCall Trace:\n ? __die+0x81/0xc3\n ? no_context+0x194/0x350\n ? do_page_fault+0x30/0x110\n ? async_page_fault+0x3e/0x50\n ? sk_psock_strp_data_ready+0x23/0x60\n virtio_transport_recv_pkt+0x750/0x800\n ? update_load_avg+0x7e/0x620\n vsock_loopback_work+0xd0/0x100\n process_one_work+0x1a7/0x360\n worker_thread+0x30/0x390\n ? create_worker+0x1a0/0x1a0\n kthread+0x112/0x130\n ? __kthread_cancel_work+0x40/0x40\n ret_from_fork+0x1f/0x40\n\nv2:\n  - Add IS_ICSK check\nv3:\n  - Update the commits in Fixes","modified":"2026-04-16T04:38:06.657270689Z","published":"2024-11-21T18:17:08.357Z","related":["SUSE-SU-2025:0289-1","SUSE-SU-2025:0428-1","SUSE-SU-2025:0499-1","SUSE-SU-2025:0557-1","SUSE-SU-2025:20165-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20248-1","SUSE-SU-2025:20249-1","USN-7276-1","USN-7277-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53091.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44d0469f79bd3d0b3433732877358df7dc6b17b1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6781cfa93a6a1b7f5be6819a5a2dd8f30f47ca26"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a078a480ff3f43d74d8a024ae10c3c7daf6db149"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53091.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53091"},{"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":"94531cfcbe79c3598acf96806627b2137ca32eb9"},{"fixed":"a078a480ff3f43d74d8a024ae10c3c7daf6db149"},{"fixed":"6781cfa93a6a1b7f5be6819a5a2dd8f30f47ca26"},{"fixed":"44d0469f79bd3d0b3433732877358df7dc6b17b1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-53091.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"}]}
