{"id":"CVE-2026-98353","summary":"RDMA/erdma: Use IRQ-safe XArray helpers for QP and CQ tables","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/erdma: Use IRQ-safe XArray helpers for QP and CQ tables\n\nLocked QP and CQ lookups from EQ interrupts can deadlock with\ncreate-path XArray updates. If an interrupt arrives while the create\npath holds the plain xa_lock, the lookup spins forever trying to\nacquire the same lock.\n\nUse IRQ-safe XArray helpers for all QP and CQ create-path updates,\nincluding the GSI QP store and error paths. Initialize both arrays with\nXA_FLAGS_LOCK_IRQ so sleeping allocations preserve interrupt state.","modified":"2026-10-08T02:52:58.193848715Z","published":"2026-10-06T08:46:40.955Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98353.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/00baeade709fb66da647e8327e8398bb532e30f7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74d4085221a7ec5440996af199ccadfa75b9eb0e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98353.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98353"},{"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":"4545f355654d044d35a31cd01cc46f491a8a7c36"},{"fixed":"74d4085221a7ec5440996af199ccadfa75b9eb0e"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"98df2aee1459ee1c62c70cbe9b370d2a532aea36"},{"fixed":"00baeade709fb66da647e8327e8398bb532e30f7"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7.2.6"},{"fixed":"7.2.8"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.188"},{"fixed":"6.2"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.157"},{"fixed":"6.7"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.12.110"},{"fixed":"6.13"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.18.52"},{"fixed":"6.19"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"610ef81797bb4f709e8675c1d8d093bb9ccdcbd8"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c0a83f29a24c7e7f8516630848ef6db4c174deed"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"05b8ca493dd02319bca93c640b259c2ba51ef321"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1fc9c1933959d2776a1ce7bf424251b8b5b586cd"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6e32f84b63c054e09392153125d7202abab2d14b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ec987c0654651036dad6a42f7fa2a6d7c16a3687"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c92686867638cda954fdb2bdbac8a75e3aa6eaae"}]}],"versions":["v7.2.7","v7.2.6","v6.1.189","v6.1.188","v6.6.158","v6.6.157","v6.12.112","v6.12.111","v6.12.110","v6.18.55","v6.18.54","v6.18.53","v6.18.52","v7.2.9","v7.2.8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98353.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.3-rc1.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98353.json"}}],"schema_version":"1.9.0"}
