CVE-2026-53030 Details
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.
A memory leak vulnerability has been identified in the Linux kernel's I3C driver for Renesas controllers. The issue arises because the 'xfer' structure, allocated by the 'renesas_i3c_alloc_xfer()' function, is not freed in the 'renesas_i3c_i3c_xfers()' function. This oversight can lead to increased memory usage over time. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed by modifying the I3C driver to include the appropriate cleanup attribute, ensuring that the allocated memory is freed when it is no longer needed.
