DynamicTablesPkg/AcpiFadtLib: Preserve platform flags on Arm and RISC-V

2026-09-25T15:32:56+00:00

BuildFadtTable() adds platform-provided fixed-feature flags before calling FadtArchUpdate(). The Arm and RISC-V implementations assign Fadt->Flags, discarding the flags already added by the platform. Use bitwise OR assignment to add architecture defaults without overwriting the existing flags. Leave the generation order, validation masks, ACPI revision handling, and architecture defaults unchanged. Signed-off-by: Djordje Nedic

ShellPkg/AcpiView: Add parser for BERT ACPI table

2026-09-25T14:49:14+00:00

The Boot Error Record Table (BERT) identifies a Boot Error Region containing platform error records produced during a previous boot. Extend AcpiView to display and validate BERT table fields. Validate the Boot Error Region length and address, and that the entire region is reported as EfiReservedMemoryType in the UEFI memory map. Signed-off-by: Amrathesh

MdeModulePkg/UefiHiiLib: Fix memory leaks in ValidateQuestionFromVfr

2026-09-25T12:42:52+00:00

QuestionName is allocated by HiiGetString() but is not released in several code path. This causes memory leaks whenever these paths are taken. Add FreePool (QuestionName) after it is no longer needed. No functional change intended. Signed-off-by: Qihang Gao

MdeModulePkg/SetupBrowserDxe: Fix memory leak in GetQuestionDefault()

2026-09-25T12:42:52+00:00

StrValue is obtained from HiiGetString(), which allocates a new string buffer. The buffer is used to set DefaultValue->Buffer but is never released, causing a memory leak each time this code path is executed. Add FreePool (StrValue) after it is no longer needed. No functional change intended. Signed-off-by: Qihang Gao

ShellPkg/UefiShellDebug1CommandsLib: Fix memory leaks in help display

2026-09-25T12:42:52+00:00

HiiGetString() returns a dynamically allocated string that must be released with FreePool(). In MainCommandDisplayHelp() and HMainCommandDisplayHelp(), the returned InfoString is printed but never freed, leaking memory each time the help screen is displayed. Release InfoString after ShellPrintEx() in both functions. No functional change intended. Signed-off-by: Qihang Gao

ArmPkg/SmbiosMiscDxe: Handle NULL strings in SetBiosVersion

2026-09-25T12:42:52+00:00

HiiGetString() may return NULL, which would cause a NULL pointer dereference in StrCmp() and StrLen(). Add NULL checks for DefaultVersionString and Version before using them. Treating a NULL DefaultVersionString or Version the same as an empty or default version also allows the firmware version to be taken from PcdFirmwareVersionString in that case, preserving the existing fallback logic without changing behavior when both strings are valid.

ArmPkg/SmbiosMiscDxe: Free buffers from HiiGetString()

2026-09-25T12:42:52+00:00

HiiGetString() returns a pool-allocated string that the caller must release with FreePool(). Free both DefaultVersionString and Version before returning to avoid leaking memory. No functional change intended. Signed-off-by: Qihang Gao

ArmPkg/SmbiosMiscDxe: Avoid overwriting Version in SetBiosVersion

2026-09-25T12:42:52+00:00

Use a dedicated PcdVersion variable for PcdFirmwareVersionString instead of assigning it to Version. This prevents the pointer returned by HiiGetString() from being overwritten and lost. Also add a NULL check on PcdVersion before calling StrLen()/HiiSetString(). No functional change. Signed-off-by: Qihang Gao
