Doc Text:	A flaw was found in the Linux kernel's remoteproc QCOM driver. This vulnerability involves a memory leak that occurs when the system fails to properly free allocated memory during certain operations within the `qcom_add_minidump_segments()` function. An attacker could potentially exploit this issue to exhaust system memory, leading to a denial of service (DoS) for affected systems.	Story Points:	---

Description OSIDB Bzimport 2026-08-15 06:13:44 UTC

In the Linux kernel, the following vulnerability has been resolved:

remoteproc: qcom: Fix leak when custom dump_segments addition fails

Free allocated minidump_region 'name' in qcom_add_minidump_segments()
when failing before adding the region to 'dump_segments'. Otherwise,
the 'name' is not tracked and is never freed by qcom_minidump_cleanup().

Return error when adding to 'dump_segments' fails.
