{"id":"CVE-2024-38544","summary":"RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/rxe: Fix seg fault in rxe_comp_queue_pkt\n\nIn rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the\nresp_pkts queue and then a decision is made whether to run the completer\ntask inline or schedule it. Finally the skb is dereferenced to bump a 'hw'\nperformance counter. This is wrong because if the completer task is\nalready running in a separate thread it may have already processed the skb\nand freed it which can cause a seg fault.  This has been observed\ninfrequently in testing at high scale.\n\nThis patch fixes this by changing the order of enqueuing the packet until\nafter the counter is accessed.","modified":"2026-04-16T04:34:18.126319024Z","published":"2024-06-19T13:35:18.676Z","related":["ALSA-2024:5928","SUSE-SU-2024:2360-1","SUSE-SU-2024:2372-1","SUSE-SU-2024:2381-1","SUSE-SU-2024:2394-1","SUSE-SU-2024:2561-1","SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2939-1","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/2024/38xxx/CVE-2024-38544.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/21b4c6d4d89030fd4657a8e7c8110fd941049794"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b23b6097303ed0ba5f4bc036a1c07b6027af5c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/30df4bef8b8e183333e9b6e9d4509d552c7da6eb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbad88f111a1829f366c189aa48e7e58e57553fc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c91fb72a2ca6480d8d77262eef52dc5b178463a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de5a059e36657442b5637cc16df5163e435b9cb4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0e14dd35d4242340c7346aac60c7ff8fbf87ffc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/faa8d0ecf6c9c7c2ace3ca3e552180ada6f75e19"},{"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/2024/38xxx/CVE-2024-38544.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38544"},{"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":"0b1e5b99a48b5b810e3e38f1d6e0d39306b99ec0"},{"fixed":"c91fb72a2ca6480d8d77262eef52dc5b178463a3"},{"fixed":"de5a059e36657442b5637cc16df5163e435b9cb4"},{"fixed":"e0e14dd35d4242340c7346aac60c7ff8fbf87ffc"},{"fixed":"faa8d0ecf6c9c7c2ace3ca3e552180ada6f75e19"},{"fixed":"21b4c6d4d89030fd4657a8e7c8110fd941049794"},{"fixed":"bbad88f111a1829f366c189aa48e7e58e57553fc"},{"fixed":"30df4bef8b8e183333e9b6e9d4509d552c7da6eb"},{"fixed":"2b23b6097303ed0ba5f4bc036a1c07b6027af5c6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-38544.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H"}]}
