{"id":"CVE-2026-23037","summary":"can: etas_es58x: allow partial RX URB allocation to succeed","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: etas_es58x: allow partial RX URB allocation to succeed\n\nWhen es58x_alloc_rx_urbs() fails to allocate the requested number of\nURBs but succeeds in allocating some, it returns an error code.\nThis causes es58x_open() to return early, skipping the cleanup label\n'free_urbs', which leads to the anchored URBs being leaked.\n\nAs pointed out by maintainer Vincent Mailhol, the driver is designed\nto handle partial URB allocation gracefully. Therefore, partial\nallocation should not be treated as a fatal error.\n\nModify es58x_alloc_rx_urbs() to return 0 if at least one URB has been\nallocated, restoring the intended behavior and preventing the leak\nin es58x_open().","modified":"2026-04-02T17:30:25.104474145Z","published":"2026-01-31T11:42:31.689Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23037.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/611e839d2d552416b498ed5593e10670f61fcd4d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6c5124a60989051799037834f0a1a4b428718157"},{"type":"WEB","url":"https://git.kernel.org/stable/c/97250eb05e4b6afe787290e8fd97d0675116c61b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aec888f44853584b5a7cd01249806030cf94a73d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b1979778e98569c1e78c2c7f16bb24d76541ab00"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ba45e3d6b02c97dbb4578fbae7027fd66f3caa10"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23037.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23037"},{"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":"8537257874e949a59c834cecfd5a063e11b64b0b"},{"fixed":"97250eb05e4b6afe787290e8fd97d0675116c61b"},{"fixed":"aec888f44853584b5a7cd01249806030cf94a73d"},{"fixed":"611e839d2d552416b498ed5593e10670f61fcd4d"},{"fixed":"ba45e3d6b02c97dbb4578fbae7027fd66f3caa10"},{"fixed":"6c5124a60989051799037834f0a1a4b428718157"},{"fixed":"b1979778e98569c1e78c2c7f16bb24d76541ab00"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23037.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.13.0"},{"fixed":"5.15.199"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.162"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.122"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.67"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23037.json"}}],"schema_version":"1.7.5"}
