Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_rproc: Fix invalid loaded resource table detection imx_rproc_elf_find_loaded_rsc_table() may incorrectly report a loaded resource table even when the current firmware does not provide one. When the device tree contains a "rsc-table" entry, priv->rsc_table is non-NULL and denotes where a resource table would be located if one is present in memory. However, when the current firmware has no resource table, rproc->table_ptr is NULL. The function still returns priv->rsc_table, and the remoteproc core interprets this as a valid loaded resource table. Fix this by returning NULL from imx_rproc_elf_find_loaded_rsc_table() when there is no resource table for the current firmware (i.e. when rproc->table_ptr is NULL). This aligns the function's semantics with the remoteproc core: a loaded resource table is only reported when a valid table_ptr exists. With this change, starting firmware without a resource table no longer triggers a crash.

How this class of weakness works · CWE-401

Allocated memory is never released on some path, so a long-running service or a repeatedly triggered request steadily consumes memory until performance degrades or the process crashes. Attackers exploit it by simply driving the leaking path. Remediation is pairing every allocation with a release and using ownership patterns or tooling to catch what leaks.

Vendor patch git.kernel.org →
Recommended fix High confidence

Upgrade to Linux kernel 5.15.202+, 6.1.165+, 6.6.128+, or 6.12.75+ (choose the release series matching your current version)

  1. Identify the current kernel version using `uname -r`
  2. Check if the running kernel version falls within the affected range: 5.15.168-5.15.201, 6.1.113-6.1.164, 6.6.57-6.6.127, or 6.11.4-6.12.74
  3. Schedule a maintenance window for kernel upgrade
  4. Upgrade the Linux kernel to a fixed version: 5.15.202 or later, 6.1.165 or later, 6.6.128 or later, or 6.12.75 or later
  5. Reboot the system to load the new kernel
  6. Verify the fix is applied by checking the kernel version and the presence of the fix commit (198c629bd03863591f3fbf5ce8ff974a33f13dc9) in the kernel source
Caveat Standard kernel upgrade risks apply: ensure driver compatibility and test in staging environment before production deployment
