{"id":"CVE-2025-38514","summary":"rxrpc: Fix oops due to non-existence of prealloc backlog struct","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix oops due to non-existence of prealloc backlog struct\n\nIf an AF_RXRPC service socket is opened and bound, but calls are\npreallocated, then rxrpc_alloc_incoming_call() will oops because the\nrxrpc_backlog struct doesn't get allocated until the first preallocation is\nmade.\n\nFix this by returning NULL from rxrpc_alloc_incoming_call() if there is no\nbacklog struct.  This will cause the incoming call to be aborted.","modified":"2026-03-20T12:42:53.775912Z","published":"2025-08-16T10:55:01.150Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03601-1","SUSE-SU-2025:03602-1","SUSE-SU-2025:03633-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","SUSE-SU-2025:3725-1","SUSE-SU-2025:3751-1","openSUSE-SU-2025:20081-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38514.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0eef29385d715d4c7fd707b18d4a9b76c76dd5e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2c2e9ebeb036f9b1b09325ec5cfdfe0e78f357c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/880a88f318cf1d2a0f4c0a7ff7b07e2062b434a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf0ca6a1bc4fb904b598137c6718785a107e3adf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d1ff5f9d2c5405681457262e23c720b08977c11f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/efc1b2b7c1a308b60df8f36bc2d7ce16d3999364"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f5e72b7824d08c206ce106d30cb37c4642900ccc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7afb3ff01c42c49e8a143cdce400b95844bb506"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38514.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38514"},{"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":"248f219cb8bcbfbd7f132752d44afa2df7c241d1"},{"fixed":"bf0ca6a1bc4fb904b598137c6718785a107e3adf"},{"fixed":"f7afb3ff01c42c49e8a143cdce400b95844bb506"},{"fixed":"f5e72b7824d08c206ce106d30cb37c4642900ccc"},{"fixed":"0eef29385d715d4c7fd707b18d4a9b76c76dd5e6"},{"fixed":"efc1b2b7c1a308b60df8f36bc2d7ce16d3999364"},{"fixed":"d1ff5f9d2c5405681457262e23c720b08977c11f"},{"fixed":"2c2e9ebeb036f9b1b09325ec5cfdfe0e78f357c3"},{"fixed":"880a88f318cf1d2a0f4c0a7ff7b07e2062b434a4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-38514.json"}}],"schema_version":"1.7.5"}
