{"id":"CVE-2024-36281","summary":"net/mlx5: Use mlx5_ipsec_rx_status_destroy to correctly delete status rules","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Use mlx5_ipsec_rx_status_destroy to correctly delete status rules\n\nrx_create no longer allocates a modify_hdr instance that needs to be\ncleaned up. The mlx5_modify_header_dealloc call will lead to a NULL pointer\ndereference. A leak in the rules also previously occurred since there are\nnow two rules populated related to status.\n\n  BUG: kernel NULL pointer dereference, address: 0000000000000000\n  #PF: supervisor read access in kernel mode\n  #PF: error_code(0x0000) - not-present page\n  PGD 109907067 P4D 109907067 PUD 116890067 PMD 0\n  Oops: 0000 [#1] SMP\n  CPU: 1 PID: 484 Comm: ip Not tainted 6.9.0-rc2-rrameshbabu+ #254\n  Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS Arch Linux 1.16.3-1-1 04/01/2014\n  RIP: 0010:mlx5_modify_header_dealloc+0xd/0x70\n  \u003csnip\u003e\n  Call Trace:\n   \u003cTASK\u003e\n   ? show_regs+0x60/0x70\n   ? __die+0x24/0x70\n   ? page_fault_oops+0x15f/0x430\n   ? free_to_partial_list.constprop.0+0x79/0x150\n   ? do_user_addr_fault+0x2c9/0x5c0\n   ? exc_page_fault+0x63/0x110\n   ? asm_exc_page_fault+0x27/0x30\n   ? mlx5_modify_header_dealloc+0xd/0x70\n   rx_create+0x374/0x590\n   rx_add_rule+0x3ad/0x500\n   ? rx_add_rule+0x3ad/0x500\n   ? mlx5_cmd_exec+0x2c/0x40\n   ? mlx5_create_ipsec_obj+0xd6/0x200\n   mlx5e_accel_ipsec_fs_add_rule+0x31/0xf0\n   mlx5e_xfrm_add_state+0x426/0xc00\n  \u003csnip\u003e","modified":"2026-04-16T04:35:26.872939522Z","published":"2024-06-21T10:18:07.695Z","related":["SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/36xxx/CVE-2024-36281.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/16d66a4fa81da07bc4ed19f4e53b87263c2f8d38"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b0a15cde37a8388e57573686f650a17208ae1212"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc9ac559f2e21894c21ac5b0c85fb24a5cab266c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/36xxx/CVE-2024-36281.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-36281"},{"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":"20af7afcd8b85a4cb413072d631bf9a6469eee3a"},{"fixed":"b0a15cde37a8388e57573686f650a17208ae1212"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"94af50c0a9bb961fe93cf0fdd14eb0883da86721"},{"fixed":"cc9ac559f2e21894c21ac5b0c85fb24a5cab266c"},{"fixed":"16d66a4fa81da07bc4ed19f4e53b87263c2f8d38"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-36281.json"}}],"schema_version":"1.7.5"}
