CVE-2025-38428
In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - check record size in ims_pcu_flash_firmware() The "len" variable comes from the firmware and we generally do trust firmware, but it's always better to double check.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - check record size in ims_pcu_flash_firmware() The "len" variable comes from the firmware and we generally do trust firmware, but it's always better to double check. If the "len" is too large it could result in memory corruption when we do "memcpy(fragment->data, rec->data, len);"
