A logoff or\nsession replacement can consequently move an unrelated connection to\nNEED_RECONNECT or NEED_SETUP.\n\nPass the target session itself and select connections using either the\nconnection-local session xarray or the session's permanent channel list.\nUse the same association test while waiting for requests to drain.\n\nSerialize session-wide status changes under request_lock and do not\noverwrite EXITING or RELEASING. Protect the shutdown transition with the\nsame lock so a concurrent session update cannot revive a closing\nconnection."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/smb/server/connection.c","fs/smb/server/connection.h","fs/smb/server/mgmt/user_session.c","fs/smb/server/smb2pdu.c"],"versions":[{"version":"f5a544e3bab78142207e0242d22442db85ba1eff","lessThan":"0875872718b98e8530fbc634e5aa7dbd3253b80d","status":"affected","versionType":"git"},{"version":"f5a544e3bab78142207e0242d22442db85ba1eff","lessThan":"c50e628122aed077695669e25b842e778511a43d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/smb/server/connection.c","fs/smb/server/connection.h","fs/smb/server/mgmt/user_session.c","fs/smb/server/smb2pdu.c"],"versions":[{"version":"5.15","status":"affected"},{"version":"0","lessThan":"5.15","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0875872718b98e8530fbc634e5aa7dbd3253b80d"},{"url":"https://git.kernel.org/stable/c/c50e628122aed077695669e25b842e778511a43d"}],"title":"ksmbd: scope session state changes to bound connections","x_generator":{"engine":"bippy-1.2.0"}}}}
