{"id":"CVE-2024-50262","summary":"bpf: Fix out-of-bounds write in trie_get_next_key()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Fix out-of-bounds write in trie_get_next_key()\n\ntrie_get_next_key() allocates a node stack with size trie-\u003emax_prefixlen,\nwhile it writes (trie-\u003emax_prefixlen + 1) nodes to the stack when it has\nfull paths from the root to leaves. For example, consider a trie with\nmax_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ...\n0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with\n.prefixlen = 8 make 9 nodes be written on the node stack with size 8.","modified":"2026-04-16T00:02:58.635137596Z","published":"2024-11-09T10:17:50.461Z","related":["ALSA-2024:11486","SUSE-SU-2025:0117-1","SUSE-SU-2025:0153-1","SUSE-SU-2025:0154-1","SUSE-SU-2025:0201-1","SUSE-SU-2025:0201-2","SUSE-SU-2025:0229-1","SUSE-SU-2025:0236-1","SUSE-SU-2025:0289-1","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","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50262.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/13400ac8fb80c57c2bfb12ebd35ee121ce9b4d21"},{"type":"WEB","url":"https://git.kernel.org/stable/c/590976f921723d53ac199c01d5b7b73a94875e68"},{"type":"WEB","url":"https://git.kernel.org/stable/c/86c8ebe02d8806dd8878d0063e8e185622ab6ea6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/90a6e0e1e151ef7a9282e78f54c3091de2dcc99c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91afbc0eb3c90258ae378ae3c6ead3d2371e926d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a035df0b98df424559fd383e8e1a268f422ea2ba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c4b4f9a9ab82238cb158fa4fe61a8c0ae21a4980"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8494ac079814a53fbc2258d2743e720907488ed"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50262.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50262"},{"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":"b471f2f1de8b816f1e799b80aa92588f3566e4bd"},{"fixed":"e8494ac079814a53fbc2258d2743e720907488ed"},{"fixed":"91afbc0eb3c90258ae378ae3c6ead3d2371e926d"},{"fixed":"590976f921723d53ac199c01d5b7b73a94875e68"},{"fixed":"86c8ebe02d8806dd8878d0063e8e185622ab6ea6"},{"fixed":"a035df0b98df424559fd383e8e1a268f422ea2ba"},{"fixed":"90a6e0e1e151ef7a9282e78f54c3091de2dcc99c"},{"fixed":"c4b4f9a9ab82238cb158fa4fe61a8c0ae21a4980"},{"fixed":"13400ac8fb80c57c2bfb12ebd35ee121ce9b4d21"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-50262.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:H/I:H/A:H"}]}
