CVE-2022-48907 [MEDIUM] CWE-401 kernel: auxdisplay: lcd2s: Fix memory leak in ->remove()
kernel: auxdisplay: lcd2s: Fix memory leak in ->remove()
In the Linux kernel, the following vulnerability has been resolved:
auxdisplay: lcd2s: Fix memory leak in ->remove()
Once allocated the struct lcd2s_data is never freed.
Fix the memory leak by switching to devm_kzalloc().
A memory leak vulnerability was found in the lcd2s driver in the Linux kernel's auxdisplay subsystem. The struct lcd2s_data is allocated but not freed when the device is removed, leading to a potential memory leak over time. An attacker could leverage this issue in a resource exhaustion attack, where repeated loading and unloading of the lcd2s driver leads to increased memory usage, potentially impacting system performance.
