  3. CVE-2026-23282
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix oops due to uninitialised var in smb2_unlink() If SMB2_open_init() or SMB2_close_init() fails (e.g. reconnect), the iovs set @rqst will be left uninitialised, hence calling SMB2_open_free(), SMB2_close_free() or smb2_set_related() on them will oops. Fix this by initialising @close_iov and @open_iov before setting them in @rqst.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: smb: cliente: corregir oops debido a una variable no inicializada en smb2_unlink() Si SMB2_open_init() o SMB2_close_init() falla (por ejemplo, reconexión), el conjunto de iovs @rqst quedará sin inicializar, por lo tanto, llamar a SMB2_open_free(), SMB2_close_free() o smb2_set_related() en ellos causará un oops. Solucionar esto inicializando @close_iov y @open_iov antes de establecerlos en @rqst.
