CVE-2026-53030
Description
In the Linux kernel, the following vulnerability has been resolved:
i3c: master: renesas: Fix memory leak in renesas_i3c_i3c_xfers()
The xfer structure allocated by renesas_i3c_alloc_xfer() was never freed
in the renesas_i3c_i3c_xfers() function. Use the __free(kfree) cleanup
attribute to automatically free the memory when the variable goes out of
scope.
Summary dbcve.org
Memory leak in the Renesas I3C master driver where the xfer structure allocated by renesas_i3c_alloc_xfer() is never freed in the renesas_i3c_i3c_xfers() function, causing gradual memory exhaustion with repeated I3C transfers.
Mitigation
Apply the kernel patch using the __free(kfree) cleanup attribute to ensure automatic memory deallocation when the variable goes out of scope, then rebuild and deploy the updated kernel.
