{"id":"CVE-2026-98498","summary":"net/mlx5: Fix rev_entry reference leak in mlx5_tc_ct_shared_counter_get()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Fix rev_entry reference leak in mlx5_tc_ct_shared_counter_get()\n\nWhen the reverse entry is found but its counter is already being\nreleased, refcount_inc_not_zero() fails and the reference taken by\nmlx5_tc_ct_entry_get() is never dropped before falling through to\ncreate_counter.  Drop it so the reverse entry is not kept alive forever\nby a shared counter lookup that did not use it.","modified":"2026-10-20T02:30:50.292397352Z","published":"2026-10-18T15:16:30.116Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98498.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0bf6bb567f0edaa771e7dd208ef98da50e6a4485"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1f13989a0704bd98cab09f9bee63e2c8a98ad4dd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/288721013605b4e0304e10f6a087b77f71cfad11"},{"type":"WEB","url":"https://git.kernel.org/stable/c/598daa5f95883f881a54967da40ce0fdfc1fdaa8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/60eab87d0a798070bf5a856b1d9e5785ce92da53"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79a3257280a335bbebbcd10d3895e8468bdcd6ae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99d8dc51663747078c031acac32edc6d90c8f1f7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c45c997d0c27359b502587897f775c5a277f0bd4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98498.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98498"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1edae2335adfa7006853e8b427f0c7c3f46b51dd"},{"fixed":"598daa5f95883f881a54967da40ce0fdfc1fdaa8"},{"fixed":"79a3257280a335bbebbcd10d3895e8468bdcd6ae"},{"fixed":"c45c997d0c27359b502587897f775c5a277f0bd4"},{"fixed":"288721013605b4e0304e10f6a087b77f71cfad11"},{"fixed":"60eab87d0a798070bf5a856b1d9e5785ce92da53"},{"fixed":"99d8dc51663747078c031acac32edc6d90c8f1f7"},{"fixed":"1f13989a0704bd98cab09f9bee63e2c8a98ad4dd"},{"fixed":"0bf6bb567f0edaa771e7dd208ef98da50e6a4485"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98498.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98498.json"}}],"schema_version":"1.9.0"}
