In the Linux kernel, the following vulnerability has been resolved: smb: client: fix oops due to uninitialised var in smb2unlink If SMB2openinit or SMB2closeinit fails e.g. reconnect, the iovs set @rqst will be left uninitialised, hence calling SMB2openfree, SMB2closefree or smb2setrelated on the...

CVE-2026-23282

CVE-2026-23282 affects the Linux kernel SMB client (smb2_unlink). The root cause is uninitialised iov structures when SMB2_open_init() or SMB2_close_init() fails (e.g., on reconnect), which can cause oopses when SMB2_open_free(), SMB2_close_free(), or smb2_set_related() are invoked. The fix initi...

CVE-2026-23220

CVE-2026-23220 – Linux kernel ksmbd infinite loop fix : In ksmbd, when a signed SMB2 request fails verification, __process_request() triggers an error path that calls set_smb2_rsp_status() and resets next_smb2_rcv_hdr_off to zero. This loses the pointer to the next command in the chain, so is_cha...
