SUSE CVE-2025-22074

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix rcount dec/increment mismatch rcount is only increased when there is an oplock break wait, so rcount inc/decrement are not paired. This can cause rcount to become negative, which can lead to a problem where the ksmbd...

SUSE CVE-2025-22039

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix overflow in dacloffset bounds check The dacloffset field was originally typed as int and used in an unchecked addition, which could overflow and bypass the existing bounds check in both smbcheckpermdacl and...

SUSE CVE-2025-22040

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix session use-after-free in multichannel connection There is a race condition between session setup and ksmbdsessionsderegister. The session can be freed before the connection is added to channel list of session. This...

SUSE CVE-2025-22041

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in ksmbdsessionsderegister In multichannel mode, UAF issue can occur in sessionderegister when the second channel sets up a session through the connection of the first channel. session that is freed...

SUSE CVE-2025-22042

CVE-2025-38575 ksmbd: use aead_request_free to match aead_request_alloc

In the Linux kernel, the following vulnerability has been resolved: ksmbd: use aeadrequestfree to match aeadrequestalloc Use aeadrequestfree instead of kfree to properly free memory allocated by aeadrequestalloc. This ensures sensitive crypto data is zeroed before being freed...

CVE-2025-38575

In CVE-2025-38575, the Linux kernel ksmbd memory handling was corrected: memory allocated by aead_request_alloc() must be freed with aead_request_free() to ensure sensitive crypto data is zeroed before freeing. This resolves a local-attack surface (AV:L/AC:L/PR:L/UI:N/S:U) with a MEDIUM base scor...
