{"id":"CVE-2024-53233","summary":"unicode: Fix utf8_load() error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nunicode: Fix utf8_load() error path\n\nutf8_load() requests the symbol \"utf8_data_table\" and then checks if the\nrequested UTF-8 version is supported. If it's unsupported, it tries to\nput the data table using symbol_put(). If an unsupported version is\nrequested, symbol_put() fails like this:\n\n kernel BUG at kernel/module/main.c:786!\n RIP: 0010:__symbol_put+0x93/0xb0\n Call Trace:\n  \u003cTASK\u003e\n  ? __die_body.cold+0x19/0x27\n  ? die+0x2e/0x50\n  ? do_trap+0xca/0x110\n  ? do_error_trap+0x65/0x80\n  ? __symbol_put+0x93/0xb0\n  ? exc_invalid_op+0x51/0x70\n  ? __symbol_put+0x93/0xb0\n  ? asm_exc_invalid_op+0x1a/0x20\n  ? __pfx_cmp_name+0x10/0x10\n  ? __symbol_put+0x93/0xb0\n  ? __symbol_put+0x62/0xb0\n  utf8_load+0xf8/0x150\n\nThat happens because symbol_put() expects the unique string that\nidentify the symbol, instead of a pointer to the loaded symbol. Fix that\nby using such string.","modified":"2026-03-20T12:40:50.345823Z","published":"2024-12-27T13:50:20.220Z","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":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53233.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/156bb2c569cd869583c593d27a5bd69e7b2a4264"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4387cef540f36c2c9297460758cc2438305a24a0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6504dd27123966dc455494cb55217c04ca479121"},{"type":"WEB","url":"https://git.kernel.org/stable/c/89933f8ab3b4cad5ac14ea56a39947d1ffe7d0e3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c4b6c1781f6cc4e2283120ac8d873864b8056f21"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53233.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53233"},{"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":"2b3d047870120bcd46d7cc257d19ff49328fd585"},{"fixed":"4387cef540f36c2c9297460758cc2438305a24a0"},{"fixed":"c4b6c1781f6cc4e2283120ac8d873864b8056f21"},{"fixed":"6504dd27123966dc455494cb55217c04ca479121"},{"fixed":"89933f8ab3b4cad5ac14ea56a39947d1ffe7d0e3"},{"fixed":"156bb2c569cd869583c593d27a5bd69e7b2a4264"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-53233.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"}]}
