CVE-2026-64420

Summary : CVE-2026-64420 affects the Linux kernel in the Cros EC (ChromeOS) subsystem. The issue arises during driver probing where dev_set_drvdata() is set before probe success, allowing sub-drivers such as cros_ec_typec to retain a stale pointer to the device even if ec_device_probe() fails. Th...

CVE-2026-64420 mfd: cros_ec: Delay dev_set_drvdata() until probe success

In the Linux kernel, the following vulnerability has been resolved: mfd: crosec: Delay devsetdrvdata until probe success If ecdeviceprobe fails, crosecclassrelease releases memory for the crosecdev structure. However, because the drvdata was already set, sub-drivers like crosectypec can still...

CVE-2026-64393

The CVE-2026-64393 issue affects the Linux kernel ksmbd component. SMB2 SET_INFO handlers performed path-based VFS checks using the current ksmbd worker credentials rather than the credentials that opened the handle, potentially bypassing security checks. The fix captures the opener credentials a...

CVE-2026-64394

Summary: CVE-2026-64394 relates to the Linux kernel ksmbd SMB2 SET_INFO SECURITY path. The fix adds a per-handle access gate to prevent rewriting security descriptors when the handle lacks WRITE_DAC/WRITE_OWNER. Previously, SMB2_SET_INFO with InfoType SMB2_O_INFO_SECURITY could re-permission a fi...
