AZL-104675 CVE-2026-98115 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: safely drain sessions during logoff SMB3 multichannel allows requests for one session to run on multiple connections. Wait for all channels bound to a session before freeing shared session objects. A deferred byte-range lo...

DEBIAN-CVE-2026-98113

In the Linux kernel, the following vulnerability has been resolved: ksmbd: rate limit unmapped SID errors A client can include many structurally valid but unmapped SIDs in a DACL. Logging every mapping failure lets one request generate hundreds of kernel error messages. Rate limit the message to...

CVE-2026-98115

The Linux kernel contains a vulnerability in ksmbd regarding the handling of SMB3 multichannel requests. The issue arises because shared session objects may be freed before all bound channels are processed. Additionally, a deferred byte-range lock can remain counted as a running request, waking o...

CVE-2026-98114

The Linux kernel 's ksmbd component is vulnerable to an issue where the parse_dacl() function silently accepts truncated ACEs and allocation failures. This allows set_info_sec() to proceed with an incomplete ACL conversion, potentially leading to incorrect permission handling. The fix involves re...
