CVE-2022-50324

Service interruption via flash-probe memory leak

Published Sep 15, 2025 · Updated Sep 15, 2025

Memory leak in the Linux pxa2xx-flash map driver allows local users to interrupt service by exhausting kernel memory. In pxa2xx_flash_probe(), an allocated pxa2xx_flash_info object is abandoned when physical-address remapping or flash-map probing fails because the error paths return without calling kfree(). Reachability requires a PXA2xx flash device and a probe failure; public records do not establish a repeatable unprivileged trigger, limiting the documented consequence to leaked kernel memory and resulting availability loss.
